I would vote not to do so.<p>
If you dupe up from 35mm to 6x7, they will be bigger and easier to see
to the naked eye than 35mm, but, compared to 6x7 dupes from 6x7
originals, they will look weak. You may send along cover letters,
notes on the matte, etc., but those will all seem like after the fact
excuses and there is no guarantee that anyone will read your
explanantion.<p>
I would second the previous poster's advice that the best way to get
the attention of the editor is to research his/her publication/needs
and provide that if you can.

Most of these places will have a Chamber of Commerce and some
sort of visitors information center which will enable you to get
in touch with labs long before you go.<p>
About a year ago I was travelling in Europe. At the Frankfurt
airport I asked for a hand inspection and the guard just sent it
through x-ray despite my protests. ISO 100 transparency, ISO
100 and 400 bw, ISO 50 and 100 color neg were all fine but I
would not take the chance again if I had a choice. From my
experience most airport security in US will put up a fuss over
hand inspecting but if you have the film in plastic bags and
allow them to x-ray camera bags they will relent. I discovered
you just need to ask 3 times politely.<p>

I think Rollies are pretty reliable in this department; I would
suspect your lab if you had the print made. If you look at the film
on the lightbox do all the areas look sharp? If you go back to your
group photo, are members of the group in a straight line? Are
people around the edges crowding forward out of the plane of sharp
focus?<p>
If you made the enlargement yourself, maybe your enlarger is out of
whack or your neg got too hot from the enlarger lamp and buckled.
If you made the print youself you could chech alignment of
lensboard, easel and neg carrier with small spirit levels yourself.
I have found that most enlarging lenses I have used do best at f11
or smaller; I don't use them at f8 or larger f stops. I recently
replaced my old enlarger with a new one and my prints never looked
better. I am printing the same negs with the same lens; but on my
old enlarger the adjustment wheels were too worn to hold correctly.
<p>
If you still suspect your camera, try photographing a brick wall at
all f stops. I would use spirit levels to make sure wall and camera
are level and a compass to make sure film plane and wall are
paralell. With your Rollie about 8 feet from the wall the bricks
should be sharp corner to corner to see detail in the mortar between
the bricks at all F stops (probably even 3.5) You can use this film
to perform a quick "enlarger alignment" test in the darkroom. I had
a Rollie with the 75mm Planar and at F8 the corners looked just as
sharp as the center.<p>
good luck

I once loaded 120 film in a Hasselblad 220 back. It cranked and
advanced (although the counter was way off) but all the film was
out of focus. We were using a 40mm lens with strobes at smaller
apertures so obviously the thickness of a single layer of paper
is enough to throw focus WAY off.
-
I once thought a really good idea would be to hang the negatives
in one of these zip up plastic garment bags that are designed to
hold your whole wardrobe for storage. These bags have an
internal frame (to keep your negs from brushing up against the
sides of the bag) and a rail built into them to hang the clothes
hangers on; you could clip your negatives to the rail with
clothes pins.<p>
The problem with this was that my garment bag was not long
enough; for economy's sake I shoot 36x rolls in 35mm. So now I
keep clothes in it instead. Perhaps one could find a longer
garment bag. I haven't had a lot of dust problems recently
because I try to keep my work area fairly clean.<p>
If your film is getting scratched and marked in drying, perhaps
the film is rubbing together as it curls in drying? I have found
that when film drys, the outer edges dry before the center and
the emulsion side drys much slower than the non emulsion side.
Due to this uneven drying, the negs can curl and coil A LOT. If
you are hanging them with clothes pins on a line, maybe they are
rubbing together? Try hanging them further apart and hang a
heavy clip on the free end.

I have some exercise ankle weights ($10.00 US or so at a department
store) with velcro straps that I can use to weight my tripod. They
have velcro straps that I can use to fasten them onto the tripod.
The Bogen 3021 tripod is okay; with the weights it works great for 6x6
or even a small 4x5.<p>
I have (and dislike) the 3055 head with hexagonal QR plates. After 2
1/2 years of frequent but gentle use, the locking catch came apart. I
can still use the tripod and it is secure, but it is now less
convenient to use. I think is is a bad design; only a small flexible
plastic part held the locking catch in place.
-
I have ordered all kinds of film (color and bw negative, transparency,
etc., even Polaroid) through the mail and haven't noticed a problem.
If I'm going to use it in a few days after having gotten it, I don't
bother to refrigerate. If I don't think I will be using it for weeks
or months, it goes in the fridge or freezer. I let it thaw a day
before using. I just keep it out of direct light and heat and it
seems to do okay. I have used transparency film 2 years old or older
out of the freezer without problems. I seldom use film faster than
ISO 200 or 400; perhaps faster film is more sensitive.<p>
The only time I recall having fogging problems was with some tmax 100
I had with me while travelling through the desert heat of the
southwest and Mexico.<p>
There are some great bargains that can be had out there if you order
in quantity by mail. I like APX 100 in 120 size; mailorder you can
find it for less than $2.00 per roll. If you do your own processing,
paper and chemistry are much cheaper too and I find the mail order
houses stock all kinds of chemistry, paper and film that my local
supplier does not.<p>
One of the problems seems to be that some mailorder people don't tell
you if something is in stock or not unless you ask. Backordered stuff
is really kind of a pain because you don't know when it will come. I
suspect that some companies list stuff in their ads but don't really
stock it or stock enough of it; they just order it if you order it. I
used to like a low cost bw film with a wonderful tonal scale called
Fortepan (I think it was made in Eastern or southern Europe
somewhere). There were only a few places that carried it and when I
tried to order it they were ALWAYS out. Finally I gave up and started
using Agfapan.

If I am loading 35mm or 120 I try to turn way from direct sunlight
and do the loading in the shadow created by my body. If am am
working outside out of a case I keep the lid shut and turned so
that when I open it the opening is sheilded from the light. This
also helps keep dust, leaves, etc., from being blown in. I do not
leave my film (35mm, 120 or loaded 4x5 holders) in direct sunlight
ever. I haven't done the aluminum foil route, but keep exposed
film in my camera bag's film pouch or in zip lock baggies that are
stored inside the camera bag so that light can't strike them
directly. If I take the film to the lab myself it travels in my
briefcase or knapsack. If I use a courier, it goes in opaque
envelopes or in opaque cardboard tube cans that my lab uses and
reuses. These are like 35mm film cans but bigger; fit about 8 120
rolls. The lab sends my processed 120 chromes to me in them rolled
up, I send updeveloped film back to them in the same can.<p>
I have only had a problem with fogging when either A) I failed to
rewind the 120 film properly or tightly enough or B) I was in the
desert in 100 plus degrees for a week with no fridge to put the
film in. I've had a little problem with old 4x5 holders leaking
light at the corners so I avoid using the most tatty ones.

>>The tool does not decide the photograph, the photographer does.<<
<p>
But when the tool becomes overly assertive, we see the tool marks
rather than the artwork.<p>
You allusion to Gallway is only about half right. Gallway DID
use the penny whistle and this choice by a classical flautist
suprised many. But the songs he was recording were folk songs
traditionally performed by farmers with inexpensive instuments.
The penny whistle was not "another flute" to Galway, it was a
whole new instrument appropriate to the music he was recording.
If your Hasselblad is a flute, then the Diana is a penny whistle,
but it is a penny whistle with only about half the number of
fingering holes it requires to actually play a tune and has a
reed that only works intermitently.<p>
In my recollection of my postings I have not attempted to tell
others that the diana is not a camera or that creativity is
defined by the tool. But the original poster specifically stated
that he was wondering if the $15.00 plastic camera was a good
intro to medium format camera studies. I think the original
poster would be much better off saving that cash towards a low
price TLR or similar camera(as has already been suggested) if he
wants to learn about printing from larger negs. If he wants to
buy the Holga and knock around and take poorly exposed blurry
pictures, fine. But lets not delude ourselves into thinking this
is going to teach him much about the possibilities of imaging
that become availible when one switches from 35mm to MF. Correct
me if I'm wrong --- was that not the original question?<p>
The diana has nothing in common with the Imagon or other soft
focus specialty lenses. I haven't used these lenses but have
seen prints from them. The soft focus lenses seem to allow the
photographer to control the degree of softness and they certainly
allow the photographer to contol where depth of field will fall
and allow the photographer to control exposure. As an Imagon
user feel free to correct me if I am wrong about that. The diana
is not a soft focus lens, it is a lens that is so bad that they
make the film plane curved to compensate in some small way for
its inadequacies. Even fully stopped down my diana did not cover
the corners. It has it's charms and its place I guess. But a
good, fun intro to MF photography it is not.<p>
A few years ago I saw a band called Pianosaurus. They had all
toy instruments and played cover tunes. Me and my friends drank
beer and had a good time. I'd never buy a Pianosaurus CD though
-- it is just a novelty act. If you took away the toys and gave
them regualar instruments the novelty would have dissapeared.
-
This debate is interesting to me. I agree that we can make good
photographs with any sort of tool. But if the tool overtakes the
process, it probably ceases to be a tool, really.<p>
I don't know how I can explain to you guys that "creativity" and
"imagination" does not mean that you allow your tool to decide how
your photograph will look. My complaint with Diana pictures is that
they all loook like, well, Diana pictures. There has been all sorts
of fancy talk in art criticism and art education circles about using
these toy plastic cameras to "learn how to see," or "liberate
ourselves from the constraints of photography" or whatever. I feel
that philosophy is very misguided. I think most serious lifelong
students of photography go through difficult periods. But so do
painters, writers, musicians, etc. No one suggests that a musician
switch from a real saxophone to one made by Fischer Price. The
problem is that most people percieve the tool in photography as being
SO important that in order to "see different" the photographer must
switch tools.<p>
My definition of creativity? Stop switching tools. Work with the
tool you have; find out everything that you can do with it. In many
photography education programs the students are asked to commit to
one camera for a semester. Do the instuctors do this because they
want to deprive or punish their students? No. The instructors know
that creativity does not depend on tool choice, it depends upon tool
use. If you want to take a picture and you have only one camera to
do it with, you are going to figure out a way. If you are very
familiar with your tool (which you will be if you stop switching
tools and keep photographing), working with the tool will be second
nature and you can spend your energy on making the photograph, not on
choosing or manipulating your tool.<p>
As far as the political implications of being pro or con Diana
photography, well, I read Photography at The Dock by Solomon-Godeau
and Diana and Nikon by Diane Malcolm. I felt that the arguments both
of these writers were making were based on the superficial qualities
of any photographer's personal history and ouvre. Solomon-Godeau in
particular was rather relentless in categorizing some artist
photographers from history as "acceptable and correct" and others as
incorrect. For someone who identified themselves with the left,
Solomon-Godeaus arguments were EXTREMELY regimented and dogmatic.
These arguments sound good on paper but outside the paper castles of
pure theory don't really hold water. NO political philosophy owns or
controls any given photographic mode. Straight photography is not
the photography of the right wing, alternative process photography is
not leftie either. I have done photographic work for publications
that concearn themselves with the rights of workers, women and
minorities. I have donated photographs to not for profit auctions
and not for profit art education groups. THESE acts are my overtly
political acts in the public realm. Soft focus or no soft focus
becomes irrelevant in the discussion. In fact, I would argue that
the continued use of soft focus effects in portrait photography
actually harms women since it perpetuates the misconception that a
womans beauty is directly tied to having smooth skin. Maybe we need
to put away our Softars, Nylon filters and vaseline and start loving
each other with pores, wrinkles, nosehair and all.<p>
-
>>This camera has a plastic lens. What were you expecting? Something to rival a Rollei, a
Hasselblad, a Leica? You paid a buck for it. You don't
like the soft effect? Irrelevant. The tool
does what the tool does. Discover the forte of the tool,
and use it there.<p>
I don't understand this philosophy that states that artistry and
technical standards are worlds apart. Why, by these standards,
is a blurry picture considered artistic and a sharp picture
considered cold, hard, unfeeling or Nazi? Maybe I am just not
hip enough for Holga but I have done all the image degradation
stuff --- solarized prints, photo lithographs, Diana
photography, pinhole photography, etc., etc., etc. In most
cases, after a while I had to recognize these alternative
processes for what they were as I used them---just gimmicks,
really. One of the things I love about photographs is that they
are a way of storing huge amounts of visual info in an easily
shared form. After a while the soft focus, the lack of exposure
controls, etc., of the Holga/Diana just become a gimmick, blurs
and murkiness to hide the fact that all too often the plastic
camera photographer him/herself really has nothing to say. Is
that the plastic camera's fault? No. But if you are a little
bored with your photography and decide to use a plastic camera
to 'spice things up' I think you are in serious trouble. <p>The
original poster asked>> if anyone has any experiences or
recommendations
regarding the Holga or similar cameras, or just words in general
for an absolute beginner to this format.<< By this format he
meant the medium format. I second the above contribution where
someone said that the only thing a Holga had in common with
other medium format cameras is the film size and that a 35mm
camera with aperture and shutter speed controls will be a better
learning instrument. Most people seem to go from 35mm to 6x6
because they want more image quality. This increase in image
quality is apparent when you make your first enlargement. A
Holga will not give you that increase and is thus not a good
introduction to the capabilities of 6x6 for a 35mm user.<p>

exposure control = right wing politically<p>
lack of exposure control = left wing politically<p>
Excuse me.<p>
Did I miss something?<p>

I once bought a Diana at a rummage sale for a buck. I put a roll
of film in it but never printed any of the pictures --- when I
developed them I saw they were smeary, ugly, out of focus. I
then went to a photo conference and every third college student
had "haunting, evocative photos" made with the Diana. I sold my
Diana to someone for 5 bucks which probably just about covered
the initial cost, the cost of the film and developer I wasted.<p>
$15.00 for a Holga does not seem like a lot of money, but if you
want smeary, out of focus pictures can't you just put a filter
with some vaseline on it and a vignetting lens hood on the camera
you already own and get the same effect? My problem with the
Diana negs were that there were almost no exposure contols (I
think it had sun, sun behind a cloud and no sun to choose from).
So you really had little or no control over neg density. So I
was limited to printing 4 inch square if at all. The only
control I had was where I pointed it. To judge by the fellow
participants at the photo conference who had pointed their dianas
at each other (clothed and naked), their family and pets (dogs
are a popular subject of diana photography), their homes, their
parent's living room furniture, suburban shopping malls, etc.,
they already had most subjects just about covered.<p>
I'm not claiming that interesting work CAN'T be done with a diana
(or a Holga), but if the most interesting thing about a
photograph is that it was taken with a crappy camera, well, then
it is not really a very interesting photograph. In this way,
most plastic camera photography looks the same to me.<p>
My advice (feel free to ignore it) is to do the Vaseline-filter
thing first. If after three months or so you still love it, then
buy the Holga. My insubstantiated assertion for the day is that
90% of the Holgas sold are used once or twice and then end up
languishing in the closet because the owner gets tired of them.
I thought plastic camera pictures were cool when I saw them
first, but it wore off fast.

Oh; I almost forgot. If you must have the (ick!) soft focus
effect, you can use the Portriga Matte paper mentioned above (not
really soft focus, but softer than the glossy Portriga since the
surface is pebbled), try a photo matte spray (sprays on the
surface of your photo -- also hides fingerprints or bad spotting
job).<p>
More softness, if you must (ick!) can be had by holding wrinkled
saran wrap (or the nylon mentioned by D Spohn above) under the
lens. I once made a soft focus picture for a girlfriend (really
--- she insisted) by stretching wrinkled cellophane over a
cardboard frame. I cut a hole in the center of the cellophane so
the center of the image would be sharp and held it under the
enlarger lens during exposure. As an added bonus, I used a
circular dodging tool to dodge out the center while I burned in
the edges of the picture, also while using my cellophane. The
print was sharp and clear at the center, dark and blurry around
the edges. I selenium toned the result. She loved it and hung it
on her wall. I thought it looked like I had a filter that was
dirty around the edges and a serious hood vignetting problem. We
broke up, she moved away and I was relieved not to have to look
at that picture anymore.

I would second //scott's reccomendation of Agfa Portriga in
Neutol. Portiga also used to have a matte surface fibre based
print that had a very warm softened look to it that may fit
your need; I have not used it in years and do not know if it
is still availible. I think it was called PRN 118.<p>
I have also used Edwal LPD developer with the Ilford MGFB
papers with good results. LPD is one of those paper
developers with which you can vary the mix to control color.

A follow up on my enlarger story.<p>
Recently I found a like-new used Beseler 23C11 enlarger with 6x6
and 35mm carriers for a bargain price to replace my worn out
Omega. I do not yet have the lens board for 50mm lens, but the
80mm works great. The difference is night and day. The problem
wit the Omega was that the gears/wheels/etc., that adjust focus
were so worn that they would not stay tight and replacement parts
were unavailible at any price.<p>
My initial tests confirm my suspicions that a lot of my
dissatisfaction with print quality came from enlargement. I have
only tested the 80mm enlarging lens since that is the only lens I
have a lens board for at this time. Previously I stated that I
was less satisfied with my 50mm lens; I will test it again after
I get a board for it and may change that opinion. I suspect that
with the 50mm any flaws from misalignment of the enlarger would
appear worse than with the 80mm since the 50mm projects a larger
image.<p>
-
I would reccomend a more cautious approach.<p>
Remember that everything you buy will eventually have to be paid
for. You can decide to buy it on credit, but then you will be
paying %18 or so on your purchase; the long lists of cameras,
lenses, strobes, etc., all listed above will run into the
thousands even if you buy used. You will be thousands in debt
before you even find your first client.<p>
I would suggest that you try to purchase as little stuff as
possible at first. I'm afraid that until you establish a client
list and a credit history as a photographer you won't be able to
get you film on an account at your local pro shop so leave the
availible balance on your Visa for that. Remember, a lot of
your clients wont pay you right away but since you are a startup
your vendors will want payment immeadiately. The same goes for
processing and printing costs at your lab. Once you start
working those lab and film costs will mount fast enough.<p>
If you already have a 35mm SLR then make do with that as one of
your cameras. Very few portrait clients seem to want or need 16
x 20 enlargements; get your feet wet with the lower paying
clients by shooting 35mm. You can always move up from there.<p>
Your best investment will be a good handheld light meter that
can measure flash and ambient light. If you have one and know
how to use it you can deliver accurate exposures every time. I
use the Sekonic Flashmate l-308b which is great and costs around
$250.00 For portraits I have used inexpensive strobes like
Vivitar and Sunpak that you can mount on a lightstand with an
adapter. Rowi makes a PC cord splitter that allows you to plug
2 flash PC cords into 1 camera PC socket. PC cord
extensions(with a male PC on one end and a female PC on the
other) to go from the flash to the camera are cheaper for
outdoor daylight portraiture with flash fill than slaves.
Indoors, flash can be bounced off a white ceiling, umbrella,
white foamcore, etc. A tripod you probably already have. If
you have the money for a medium format camera, I would reccomend
one which can take a Polaroid back. I use my Hasselblad with
Polaroid back to do tests for my 35mm camera.<p>
I guess my list would be 2 flashes (like Vivitar 283), 4
lightstands, battery packs for flashes and modules, little
adapters and things to mount flashes on stands, some diffusion
to soften light, a big gym bag to carry all this stuff in, "A"
clamps (from hardware store) to mount foamcore refectors to
light stands. All that would probably cost already $800.00.<p>
Add to that your meter and you have a total of around $1050.00.
(These numbers are just my guess) I am assuming you already
have a 35mm camera and a couple of lenses.<p>
What you really need to do to start your business is get clients
and a portfolio together. With your minimal gear listed above
you can shoot friends, family, neigbors, etc., and get practice.
I had my own darkroom and can still use a friends in a pinch; I
find most people are willing to allow me to practice my
portraiture skills if I promise them a nice 8x10 for their
trouble. As you get satisfied customers, you can keep adding to
the portfolio; just ask if you can keep a copy of a portrait as
a sample; most people will be flattered.<p>
There are other costs you will want to consider: business cards
are very important. You will get a lot of business from
personal referrals; if you can pass out a card saying who you
are and what you do with a number people will start to call. I
give out cards all the time; it is a cheap way to advertise
yourself. I bought a rubber stamp with my name and phone
number; every print gets stamped on the bottom corner on the
back (hint: don't stamp in the image area (it may show through)
and don't stack stamped prints till ink is dry). Even if they
lose my card, they still know who took the picture and how to
get in touch with me. I also stamp the envelope I put the
pictures in for delivery. Some people have fancy matts with
gold stamping, etc., too; those can be kind of expensive if you
buy with your name custom imprinted.<p>
Photo businesses and restaurants have a huge rate of failure;
mostly because people love the craft of photography and cooking
but they don't think ahead about initial costs vs. income over
time or how they will find customers. There are a LOT of books
on how to start a photo business; I think you will get more
knowledge from part-timing your business at first and minimizing
your initial investment, expanding your investment as you grow,
or, better yet, consider assisting an established photographer
for a while before you go off and start your own business.<p>
-
Is there some reason you don't want to use strobe and prefer
continual light sources?<p>
Strobe, for people shooting, I think is the way to go. Perfectly
balanced for EPP, E 100s, Provia; any 120 slide film you care to
use. Also perfect for any color neg film. A Hensel or Norman
400b are very portable, and, with a fast shutter speed, will
easily overpower off color ambient light from streetlights, etc.,
that may throw color balance off.<p>
HMI lights are really expensive to rent or to own ans you will
need a generator to keep them going unless you are shooting right
outside your front door and can run extension cord. I know of no
battery pack for HMIs. HMIs are also HOT, delicate, heavy (each
light requires its own transformer), bulky, expensive; a real
bother. I wpuld only bother with them if you were shooting cine
film or with certain kinds of digital scan backs (although the
scan back WOULD NOT work for models wearing fashions downtown at
night).
For still photography, Tungsten lights are a cheaper alternative.
They are not truly flicker free (like HMI) but constant enough
for still photography. These also require a generator, but you
can rent a smaller, gas powered model. You can even buy tungsten
bulbs with standard light bulb sockets and put them in cheap
reflectors from the hardware store; not the most elegant solution
but cheap. I have used Tota and Omni lights to shoot portraits
with ISO 50 film and full blue gels on my lights. I recall that
I had to ask my subject to keep very still; in order to get f8 or
so I needed a shutter speed of 1/4 or 1/8 a second as I recall.
They are not the brightest light source. You can use them with
Tungsten balanced film with no filtration. If you want to use
them with daylight film,; you will need to either put an 80A
wratten filter on your lens (eats up about 2 stops of your
exposure) or blue gels like the Rosco 3202 full blue (eats up a
lot of your light). I prefer to gel the lights because the 80a
really darkens the viewfinder of my slr. Some people say if you
are using color neg to forget the blue filters and correct at the
lab; I think that is a bad idea.<p>
If you want to shoot outdoors at night and need to be portable, I
think battery powered strobe like the Normans or the Hensel is
the way to go. I have even used a Vivitar 283 with a Quantum
battery pack with good effect. With tungsten or HMIs you will
also probably need lots of permits from the Police, property
owners and public officials; if you use the portable battery
pack, depending upon where you are shooting you can be done
before anyone gets bothered. If these photos are for a client
(and not just for your personal portfolio), you will need
property releases as well.<p>

I had a Yashica LM with 80 f 3.5 Yashinon years ago. The meter didn't
provide accurate readings but the lens made wonderful black and white
prints. I went as large as 14 inches square with the prints. The
lens seems to perform best at f11 or so; at f5.6 and larger I recall
it got a little dark and smeary at the edges. After the film advance
went out the camera was shot, but I ran 100s of rolls of film through
it for 2 or 3 years; for what I paid for it, this was a bargain.<p>
If you don't know how to load/work it, email me back and I'll try to
fill you in. The Yashica uses Rollie Bay 1 accessories. They make
all kinds of filters (some still new), lens shades (a good idea with
this lens) wide angle and tele attachments (the results are not so
impressive. With the wide angle, all around the edges seems soft; the
center is barely acceptably sharp. If you want wide angle, put a 28mm
lens on your 35mm camera. Instead of useing the 'Sun' brand tele
attachment, I would get better results by enlarging the center portion
of neg.). For a little less than the price of your Yashica, get a Bay
1 Rollinar. The +1 and +2 Rollinars are great close up lenses. I
also has a Rolinar +3 but almost never used it. Rolienar +1 allows
you to focus on objects about 1 1/2 to 3 feet away, Rollienar +2 for
objects 1 to 1 1/2 feet away. The Rollienars have a parralax
compensating lens that you put on the viewing lens; if you mount it so
the red marker dot faces up what you see in the VF is VERY close to
what you get. It is amazing. They worked great on my Rollie; I don't
see why they shouldn't work on your Yashica. When the Yashica started
wrinkling my film, I replaced it with another camera but the Yashica
remains a great bargain. I would also snip out a small filter from a
Kodak gel filter and fasten that Inside the camera behind the camera
lens for when I wanted 81a or something on the lens.<p>

I am not a camera dealer, but when I was shopping for a
Hasselblad set up similar to yours here in the US a few months
ago everything seemed to be priced about 30%-40% more than the
prices you quote.<p>

Roger;<p>
The illustrations would mean nothing in comparison to your own
lenses unless you did the test yourself exactly as I did mine.
They would also be a great deal of trouble to provide since in
order to show such fine detail I would have to enlarge the tiny
(about %5) portion of the 35mm neg that contains the test chart
(most of the picture is blank wall) hundreds of times. To give
you an idea of how tiny the chart is, pin a 6x6 card to your
wall. Put any focal legnth lens you care to on your 35mm.
Multiply the focal legnth X45 and place your camera that far from
the wall in mm. No matter what focal legtn you use, the card will
always be the same size(that is the best thing about this test).
It will also be very small in the frame. In order to give you a
jpeg on which you could read the grain, I would have to create a
HUGE file. I don't know if jpegs (even huge ones) could show you
the photographic grain very well. In order to see it, I had to
raise my enlarger head all the way up and view the test target
with a grain magnifier (which has -- I dunno 10x magnification as
well? more?). Even then, making out the really fine lines was
difficult.<p>
If you simply must see the film, drop me a line and I'll snip a frame
a frame and send it to you.<p>
The point of this test was not to prove that my lenses were
better than yours. The point was to see how well my stuff works.
I still get pictures that I am not technically happy with; I am
trying to narrow the causes. I discovered that of the 6 35mm
lenses I tested (4 that I use and 2 as controls), the 4 I use
come out about the same. My test showed me that even a little
bit of overexposure causes a greater loss of resolution than
switching from an A+ lens to a D- lens.<p>
For the many people who have been sending emails asking, the film I
used was
Tmax 100 in tmax developer 1:4 at 68 for 10 mins. I'm sure there are
finer grain films that would extend the test further; I don't think I
need to go there. The test chart is the one on page 54 of Ed
Romney's book that I mentioned in the text. Your mileage may vary.<

In my description of my test I may have been a little hasty in
condemning my other enlarger lenses; does anyone know of a good
way to test enlarger lenses? I tried the 135 Schneider again; it
seems pretty good but I suspect an alignment problem. One way to
test this, I guess, is to photograph a flat paper covered in
stripes or graph paper, develop the film and see how sharp and
straight the lines are from edge to center. Anyone have any
better ideas?<p>
To answer the question regarding whether I used the best aperture
of my enlarger lens; I put the negs back in and looked again at
all apertures; it made the image darker but I would not change my
judgement of the results. Maybe I would if I had that 100x
microscope.
Part of my problem is that I really don't have the time or
inclination to invest in darkroom stuff right now; I am currently
interested in making lightjet prints instead of tray process
prints but would just like to know how well this stuff works for
when I move into a new place where I can build a darkroom.<p>
The hasselblad suprised me, not because I thought it did badly in
the test, but because I thought in fact it did very well. It
tested right around the better 35mm at smaller f stops and fell
off as I opened up. I had been told that MF lenses were awful
compared to 35mm but this seems to indicate otherwise. For the
record, my Planar is the older 80 f 2.8 C lens, not the CF. I am
told the CF version has 1 or more extra elements to improve
performance at larger apertures. Sadly, I sold my Rollieflex to
buy the Hasselblad. I wish I had been able to keep them both but
needed the interchangeable backs and Polaroid capabilities of the
Hasselblad and couldn't afford 2 MF cameras.

I've just noticed that the upper flap of my second shutter of my
500c hangs a bit low. The end of the flap hangs about 1/4 inch
down from the mirror after the shutter has been fired. As I
recall, it used to rest flush against the back of the mirror
when the mirror was in 'up' (exposure) position. Pictures
seemed okay the last time I shot film (less than 1 week) but as
I look at it today it definitely will block exposure of a part
of the frame.<p>
Has anyone else encountered this? Do you know of anything I can
do?

Months ago I promised other forum contributors that I would come
up with my own lens test. I have been critical of lens testing
in my postings in the past; I still think a lot of these tests
really skew the results because of the way in which they are
done.<p>
I think at this point I have come up with a test that works
pretty well and doesn't require a lot of fancy equipment like
lasers or $3000.00 collimators. I have written a description
located in <a href="http://www.icon-stl.net/~stefan/
sworn_enemy.html">http://www.icon-stl.net/~stefan/
sworn_enemy.html</a>.<p>
If you just want to see my numbers, go to <a href="http://

~stefan/results.html</a>.<p>
Some of the results suprised me. Conventional wisdom states
that MF lenses are less capable of rendering extreme detail than
35mm; in other words, a MF camera depends heavily upon its
larger film size for the better prints you can expect from it.
In my test, my 80 f2.8 MF tested about the same as 50mm primes
for 35mm at smaller f stops.<p>
I would be interested in others views of both my test and the
results.<p>

Duplicating 35mm slides to MF slides for Image Editors

New info on your old question. I'm afraid I was only about 1/2
right on my previous posting. Recently I had a chance to talk to
a photographer who has been making his living shooting stock and
assignment photography for magazines for 20 years. He said he
almost always uses 35mm; he uses 90% slide film and the rest is
BW. He said his preference is to send original 35mm chromes; if
he can't or does not trust the magazine not to lose the original,
he sends a 70mm duplicate. Since he often sends the same film
out multiple times to different clients, he makes multiple
"originals" in the camera at the time that he takes the originals
if possible. They are supposedly better than any copy and I
figured out if I buy my film in bulk at have it processed at the
local lab it runs less than 0.40 cents per frame --- cheaper than
any duplicates.<p>
This guy was careful to say that I should not confuse "display"
dupes with high quality dupes. Display dupes cost about a buck
each and are just to show someone to give them an idea of what
you have. The high quality dupes cost $25.00 or more and can be
used by the printer to produce the printed piece. The
photographer told me that he uses the high quality dupes you
mentioned when he has a one of a kind piece of film. He said
that he has a few clients that he deals with on a regular basis
that he trusts not to lose his pictures and he usually send them
the originals. In 20 years and hundreds of submissions a year he
said he had only had his film lost or damaged a handful of
times.<p>
