Pete:
<p>
The reason for concern I would assume, is for macro work, where a
spot meter might be advantageous for small areas at close distance.
<p>

While the meter doesn't care if the image is in focus, an out of
focus image will not be metered as accurately. Say a high value and
low value are adjacent. If the image is out of focus, the
values "dilute" each other and your metering is out of focus.
<p>
Yes, a close up lens will help. Note that the meter, though, doesn't
account for reciprocity failure nor bellows factor.
<p>
The close up lens will also help you see what you are aiming at.
-
You can:
<p>
1. Open up (stop down) the lens 1/3 stop from the 400 speed to
represent 1/3 stop slower (faster) film, i.e., 320 (500).
<p>
OR
<p>
2. Change the film speed on the meter and re-read. If light hasn't
changed, you should get the same net exposure. If you don't your
meter isn't linear, and needs fixing or replacing.

Keeble & Shuchat in Palo Alto has a very complete darkroom &
professional department. In addition they do all the consumer stuff,
too. They carry quite a bit of Photographer's Formulary chemistry.
<p>
San Jose camera usually has the best prices on equipment, but isn't
as well stocked for pro & darkroom stuff.
-
T-Max, if I recall, is intended for single use. T-Max RS is a
replenishable developer and can be re-used. Kodak's info sheet
provides details on this.
<p>
Any fixer can be used more than once.
<p>
Developer can safely be put down the drain. Fixer contains silver, a
metal contaminant and should not be put down the drain in some areas.
It depends where your drain water goes. I live in the San Francisco
bay area, and waste water ends up in the bay. Fixer is not permitted,
but our county hazardous waste recylcing facility accepts it. Check
with your county or city hazardous waste department for information.
<p>
Fixer can be put down the drain if the silver is removed, but this
involves some equipment and may not be worth the cost or trouble
unless you use lots of it.
-
If you can use 120 size, use Verichrome Pan. Filters would depend on
the background, but probably not. Fill flash, depends on the nature
of the existing light. Generally not if you've got soft light.
-
I concur with Carl. The Ries J will hold an 8x10. But I recommend the
Bogen 3057 head.
-
If the 203 produces results comparable to your current 135 Caltar II
S, then keep the 203. If the results are not as good, consider
replacing it. Also, if you're having shutter problems you might
consider replacing.
<p>
But if your results are good and it performs well, why replace it?
-
I've dealt with Calumet for longer than I care to remember--at least
as far back as mid 70's. They've got decent customer service, so
here's a plug for them and having these lenses at very nice prices!
-
I'd tell you but you're better of if you figure it out yourself. I'll
give you a hint: It won't work.
<p>
Try it using a sheet of photo paper and report your results.
-
Your question is a little ambiguous.
<p>
Are you looking for a VC head with blue & green grids, or a single
grid suitable for use with VC filters.
<p>
Usually the "high intensity" lights are blue only, not suitable for
use with VC papers.
<p>
To my knowledge the W54 lamp is not available from Zone VI, only from
Aristo directly. But I suggest you contact Calumet (owners of the
Zone VI name) and discuss with their sales staff. Since they sell
both, they could identify which product best suits your needs.
-
There is a chance you have bad lenses. They don't all come out
perfect! Take Bob Solomon up on his offer to check your lens out.
<p>
(Having 2 bad lenses, each from a different supplier seems unlikely,
but it is possible.)
<p>
Charlie
-
Finally, if you can afford it, Calumet has the Caltar II 135/5.6 for
$470ish. It's a Rodenstock Sironar, and a bit longer than you're
looking for, but I've always likes Sironars.
-
A friend gave me a 90mm Schneider Angulon (not Super), and it's
performed very well for me. Apparently some Angulons are better than
others. Get a money-back-if-not-not-satisified guarantee, which I
recommend for all used lenses. Be sure the lens is coated if you buy
an Angulon.
-
Since we haven't nailed it yet, look for the obvious.
<p>
1. Using a tripod with the 4x5? Is it heavy enough to stabilize the
camera?
<p>
2. Any chance of camera motion?
<p>
3. Any chance of subject motion? (You didn't say what the subject
was.)
<p>
4. Using a cable release?
<p>
4. Do the lenses project a sharp image? Try this at night: open the
shutter, and focus the image of a bright light source (street light,
moon, porch light, whatever)on a matt sheet of paper--can you get the
image in focus?
<p>
Do you have an experienced LF friend close by who could look at your
equipment & technique?
<p>
While MF lenses are better than LF, no way should any LF negative
have unacceptable sharpness when things are aligned & used right. My
simple 4x5 portraits just bowl me over compared to MF & 35mm. In
fact, I think LF has generally been underappreciated in portraiture.
Suberb tonality and detail. Sorry you're not seeing it yet.
<p>
If, by chance, you're in the SF Bay area, & you can't figure it out,
I offer to meet you to help see what's going on.
-
Sorry, but the lifetime warranty went away with Fred Picker. Calumet
no longer provides this, but I believe they honor the warranty for
people who bought from Zone VI.
<p>

I owned a Zone VI-II 5x7 for a few years, but sold it.
<p>
I didn't see any deterioration in the foam over those years, but I've
seen it happen on many other products with foam. The problem, from
what I've heard, is that there is a fungus that attacks the foam and
deteriorates it. You should inquire with Calumet to see if they
incorporate a fungicide in the foam.
<p>
While the Zone VI performed well for 4x5 (and I didn't use the "out-
straight" carrier) I had the following complaints.
<p>
1. The lens height adjustment lost its grip, especially with high
compression of the bellows. Ask Calumet to show you (not explain) how
the adjustment is made to tighten this. Unless you're hands are half
the size of mine, you won't be able to get at it. You'll be lucky if
you can even find someone at Calumet who can tell you how to adjust
it. Their tech support on these products stinks.
<p>
2. If you follow the wall mount kit instructions provided (at least
at the time I bought mine), the turnbuckle rods will form an arc. I
tried to explain this to them over the phone to see what I did wrong,
and couldn't get a competent response. Again, the Zone VI tech
support is less than admirable.
<p>
3. For anything negative smaller than 4x5, the enlarger is mediocre.
The light is dim, and it's difficult to focus and compose.
<p>
Simple math explains part of the problem. The following shows the %
of total light output used for each image size.
<p>
4x5 = 57%
6x9 = 23%
6x7 = 18%
6x6 = 15%
4.5 x 6 = 11%
35mm = 3%
<p>
The other part of the problem is the eye is most sensitive to yellow
light, and the enlarger produces virtually no yellow light.
<p>
The VC head, however, was easy to used & very consistent.
<p>
My current enalrger is a Saunders 4500-II and I like it much better.
-
I've used Orbit bath, and treat it as if it were Kodak's Hypo
Clearing Agent. No problems.
<p>
The film times are OK to use, but I invariably wash my film longer,
since I use the wash time to clean up the darkroom and that always
takes longer than 5 minutes.
<p>
The only time I'd use a wash as short as 5 minutes for paper is for
RC. For FB, follow the HCA instruction. I doubt it can wash DW FB
papers in 5 minutes.
-
This is a process of eliminating variables to find the culprit.
<p>
Check the negative itself, not the print. Is it sharp? (Using
transparencies as suggested is also an option). If the negative is
sharp, then the fault lies in the enlarging process, not the camera
nor camera lens. Problems can be ... well, you probably know what can
cause an unsharp enlargement. Post again, if you don't.
-
The other posts are right. But, don't use regular fixer for 15
minutes. That's over fixing, and likely to start damaging the image.
<p>
You can try HCA (hypo clearing agent) first to see if it clears. If
it doesn't, rinse for 5 minutes, then re-fix, then HCA, then wash.
-
There are no real practical differences among the materials for a
home darkroom. For a professional, SS probably holds up better for
sheer abrasion resistance.
<p>
The best sink is the biggest you can fit in your darkroom that you
can get at the best price.
<p>
Check Calumet, Delta, Leedal, and Arkay. Any may have overstock, or
something custom that was cancelled for the best prices. Some of the
bigger dealers might have stock, too, and it's been around long and
hasn't sold, they'll probably give you a good price for it.
<p>
I bought fiberglass (Arkay). It fit best, and cost the least for what
I got. Make sure the SS is photo-grade (usually 316L). That makes a
big difference. Other grades won't hold up to the chemicals.
-
Built my darkroom about 5 years ago and did some serious work on
investigating sinks.
<p>
1. There is no bargain SS sink.
<p>
2. The alternative I found was a 7' x 2' fiberglass sink from Arkay.
It cost me about a grand & included stand. It has a nice built-in
backsplash. I couldn't do any better. Seven foot seemed odd, but
turns out to be very practical. I'm glad I got exactly this sink.
<p>
Things to consider.
<p>
*I had a specific space to fit. Getting more space was my most
expensive option, so I spend more on the sink than I wanted. I would
have like a 30 or 36 inch depth, but have found I don't miss it. If I
ever decide to do a lot of 16x20's, I figure I can buy SS trays that
will fit. They are expensive, of course, but cheaper than finding
more space for a 30 or 36 inch sink.
<p>
MOST IMPORTANT: Design your layout on paper. Do this about a dozen
times over to make sure you've got the design that's good for you.
Then see what equipment fits. Make a template on cardboard of the
layout, and make paper cut-outs of the equipment to see how it fits.
<p>
Watch out for ABS plastic sinks. The material is fine, but Delta, for
example, has spots for faucets that reduce the width in different
places. Where the reduction occurs, you can't fit bigger trays, so it
wastes space. This is where the cutouts can help you.
<p>
Make your aisle at least 3 ft wide between wet & dry sides. Give
yourself enough space to breathe & be comfortable. Think about enough
room for 2 people in case you want to teach someone or show a friend
your process.
<p>
Safelights: I bought a Thomas Duplex. Big mistake. Too much light. I
found an Aristo Red safelight on EBay for $50. Very nice. Even at the
new price, I think I would prefer it. I like red, but not everybody
does. Thing is, it's safe for virtually all B&W papers. Not all amber
lights are.
<p>
Make sure the working surface height is good for you. Make it too
low, and you'll get a backache.
<p>
If you're in the SF bay area, come see my darkroom. You'll figure out
what you like & don't.
<p>
I've got lots more suggestions, but am rambling.
-
I like the Toyo 45A-II. I've owned it's older version the 45-A since
the mid 80's. A very rugged, stable little beast. Great for
landscapes, but limited close-up capability. Choose a shorter lens
for macro work.
<p>
To do it right, however, go to a camera shop & try each out. It's the
only way to find out if the camera is right for you.
-
The Zone I exposure from your zone system film speed test gives you
the info you need to make your pre-exposure. Pre-exposure is most
easily done in-camera.
<p>
Without knowing your own film speed, you can't really account for
variables, such as shutter efficiency and accuracy.
Self-Loading Film
in Black & White Practice
Posted
If you are really looking to control development of individual images
you are a candidate for large format using sheets (or roll film
adapters with individual adapters for different development times).
<p>
That said, bulk film for 35mm is fine. Keep everything clean, and
prepare to waste a couple of extra images at either end of the
cassette for frames exposed in the loading process.
