Salt spray has cost me $300 in repair bills to a P67 some years ago,
and I know of others who have had similar problems.
<p>
Your LF camera does not have the sensitive electronics, but the
camera and lens will suffer if exposed to salt spray. I live on an
island, and the coastline is never far away, and even when you think
there is no spray, there is. Take a stroll with a pair of glasses at
what you think to be a safe distance, and look at the lenses after an
hour or so and you'll see what I mean.
<p>
Shoot with a longer lens if possible, or protect with plastic and UV
filter. That's an expensive piece of gear you have there, and no
point mucking it up if it's avoidable.

You're not likely to get much more from a digital camera as a meter
than you would a spot or ambient meter. The reasons are the latitude
differences, and the way the LCD shows the scene.
<p>
Depending on your film, you will likely have a fair difference in
what the camera can record or show on the LCD, and what your film
actually records. You could experiment with different combinations of
digital cameras and film until you found something suitable, but it
seems like a lot more work than simply knowing your film and meter.
<p>
As to the in camera histogram, it is very valuable to show what's
blown out for the digital camera, but that may not translate directly
to the film you're using. Hope this helps.

Film died for me some time ago .... my LF camera is on it's deathbed.
What I cant' do with digital and computer perspective correction is
very little. But then I'm a commercial photographer and cost and ease
of use are strong considerations for me. My best and most enjoyable
photographic moments were with a LF camera, and for many others on
this site and around the world. For that reason, and also for the
joys of printing your own work, film will live for others for quite
some time yet.

Richard has the idea, but I'm unsure of how you're going to get the
sepia toning with PS 5 without a computer.
<p>
There were several models which offered in camera sepia toning, and
along with a printer, you'd be in business. Make sure the camera is
of the DPOF class, which allows direct printing.
-
Lee, talk to your print shop first - they will tell you what scan
resolution and file type are required based on the print size and
quality you want.
<p>
There is no way to get a quality 20 X 24 from a 30MB file.
-
You could send me the camera for a free evaluation of the required
maintenance and suggested intervals.
<p>
This evaluation can often take three to five years, and would require
frequent use of the camera. Please send film as well, I have my own
holders and meter.

I don't think we've lost anything - if the image is the most
important thing.
<p>
I'm sure many of these Speed Graphic 40's and 50's shooters would
have traded their gear for a Nikon in a heartbeat because they were
result driven.
<p>
Yes, given the equipment limitations their shots by necessity had to
be better timed and considered and you have to admire them for that
but I wouldn't raise it to an art form.

Welcome to LF photography. You would set your lens to the widest
aperture to give a brighter groundglass image for initial focusing,
and recheck at the actual shooting aperture with a loupe and
darkcloth.
<p>
You can make the whole focus and movements thing as hard or easy as
you like ... Merklinger is certainly the hard way, perhaps made
easier with a masters degree in math, although his website used to
contain short video clips which are helpful.
<p>
Remember this little ditty .... " Focus on the far, tilt for the
near, then focus and tilt 'till all is clear ". In your example,
focus on the distant horizon, then tilt the lens panel foward, or the
film panel backward to acheive focus on the near object. Bottom line
is it isn't rocket science, and after a few hours behind the
groundglass actually seeing the effect of movements, you'll get the
hang of it. Others take a much more measured approach. Try simple
first, and if you're not happy with your results, change your
shooting method.
<p>
The Simmons book you have ordered is often mentioned as an excellent
source, as is Strobels " View Camera Technique "
<p>
Perhaps the most valuable LF resource is this forum ... the archives
are a goldmine of information, and the members helpful.
-
see http://www.imaging-resource.com/
<p>
very complete and current reviews. also links to other sites and
forums are there as well.

Kodak has been run by the accountants and their bottom line for many
years, and the firm goes wherever the profit is.
<p>
I for one would not miss them or their products one bit, in fact were
the yellow devil to quit the film business it would be good for the
remaining film companies, perhaps permitting them to expand their
product lines.
<p>
While they discontinued wonderful emulsions such as Ektar they put
R&D and massive marketing expenditures into their consumer 'Max'
films, along with digital consumer products. We should all be lucky
enough to dance on Kodaks' grave.
-
Funny stuff, probably a lesson learned - I ordered a lens overseas
and the eager customs staff actually unscrewed the rear element, and
the brass spacers fell out. Instead of trying to put it back together
they just threw it all back loose in the box !!!!
<p>
SK Grimes will put things right for you.
-
I absolutely enjoy every part of the LF image taking process -
setting up, leveling, focusing, looking at the GG, mucking around
with the movements, metering, setting the lens, etc. I've even grown
fond of the strange looks you get from some folks when you pop your
head out from under the darkcloth. The whole process is simply
enjoyable - like a vacation.
And increasingly LF is a process for me, not a result. And once you
look at an image on the GG, other viewing alternatives seem puny and
inadequate.

I've used a 90mm SA with the Discovery, and found the standard
bellows fine for most shooting. You're more likely to be limited by
lens coverage than bellows. The real concern would be using
rise/fall and shift in combination with tilt/swing. You will get
binding fairly quickly in that situation.
<p>
Having said that, the leather WA bellows is a joy - long enough to
cover the 30cm rail and short enough for WA lens use. You could leave
it on all the time. Too bad you can't buy a Discovery with the
leather WA bellows as the 'standard' bellows.
-
This may sound simplistic, but shoot a few test sheets with 100F and
use color balance and hue/saturation in PS to change or remove any
unwanted color casts.
<p>
With some practice and patience I've found very little that cannot be
color corrected in PS.
-
Just a quick additional word about incident metering - I'd suggest an
inexpensive incident used on every shot regardless of which final
metering method you use to arrive at your final exposure.
<p>
You will in time become very good at determining the correct exposure
based on the ambient light measured by the incident meter, regardless
of your subject reflectivity, luminence, or distance. I recall a
thread some time ago perhaps titled " the meter in your head " which
dealt with this.
<p>
I carry a Sekonic 398 incident only and have learned to use it in all
exposure conditions. An additional benefit is you learn to read and
understand light.
-
The Innu have over twenty words to describe snow, and each probably
would require different metering. As a start, eyeball the snow for
reflectivity - small frozen granules in bright sun add to the
required exposure - dry snow on a cloudy day requires less added
exposure and so on. And much depends on the effect you�re going
for, and the exposure range of the film you�re using.
<p>
Two alternatives to reflected metering of the snow would be to use
either an incident meter, or a gray card with a reflected meter. I
see snow four to six months a year, and generally use an incident
meter and would consider that to be your best metering choice,
followed by the gray card. If you have to meter the snow with a
reflected meter, 1 1/2 to 2 1/4 stops over is a good ballpark
starting range, but again much depends on the type of snow, the light
conditions, the type of film, and the effect you require.
<p>
The two hardest things to meter accurately without an incident meter
are coal mines and snow.

Finding a lab that consistently produces good results is not an easy
task. In fact, it�s one of the reasons I now use digital with
perspective correction in Photoshop for the majority of my commercial
work.
<p>
Sooner or later your lab WILL screw up - I�ve had film lost, received
the wrong film back, had processing errors of every conceivable
variety �. I�ve even had 120 film back with frames being scissor cut
well into the image.
<p>
Why does this happen ? Several reasons come to mind �. High staff
turnover, poor employee training and motivation, large volume of
work, and low wages. I�m sure you could find other reasons.
<p>
The problem you describe is a minor one - wait until they lose work
that you absolutely have to receive because your income and
livelihood depend on it. At that point you say � No more �.
<p>
I just completed a job with over 400 frames, the majority of which
have been stitched 20 to 30 at a time into a series of panoramic
movies for a clients web site. If even one of the frames is screwed
up you have to reshoot all 20 or 30 for that pano. Would I trust a
lab with that when I have a digital / Photoshop perspective control
alternative ? Not on your life. Not to mention the time and money
saved by shooting digital.
<p>
The best lab is your own - get a digital back for your LF camera, or
use computer perspective control with a digital SLR. Or explore
doing your own E6 - the sooner you can no longer depend on a lab, the
better.
-
Low end scanners will not always dissapoint, it depends on your final
output. I use a flatbed UMAX e3740 600dpi scanner fot all 4X5 scans
for web output or small print.
<p>
This sacnner bundle cost $150 Canadian, and that included PS 5.0 LE,
so the actual scanner cost about $65 U.S new. On well exposed
transparencies, it does an excellent job.
<p>
The thing to remember is a 4X5 transparency or neg has quite a lot of
information on it, and to scan at high dpi means huge file sizes,
much of which will be thrown away when you resize for final output.
<p>
Sure, if your final output is going to be larger prints, or critical
applications, a pricer flatbed will give you better bit depth and
higher DMax - and you may well need both - but depending on your
output, a low end scanner can do the job.
-
Cheap it ain't, and there are tons of Photoshop resources and forums
on the web for free - searchable and interactive.
-
Hard to say, but was there enough temperature difference to cause
condensation? Were the other chromes subjected to the same
temperature change? Test with an exposed sheet to see if condensation
forms under similar temperature change conditions. I've taken film
from the fridge, and shot within a few moments at room temperatures,
and hadn't noticed any condensation problems.
-
It would depend on the height of the structure you're shooting, and
your distance away from it. For taller buildings from a close
distance, you'll need more rise than a short building far away.
<p>
As another reply said, you'll most likely run out of adequate lens
coverage before camera limitations, but if you plan to shoot
skyscrapers from across the street, get the most movement you can
along with the lens with the most coverage.
<p>
For landscape work, your movement requirements will be modest -
you'll probably only end up using a small amount of front or rear
tilt with most shots.

BTZS tube style - check their website for more details. There are
also a number of threads in the archives on this subject, with many
good ideas.
-
Strobels� �View Camera Technique� offers good information on the
subject. The following two links offer interesting information:
<p>
http://www.luminous-landscape.com/dof.htm
<p>
http://www.luminous-landscape.com/dof2.htm
<p>
See also the rather lively discussion thread in the general forum on
that same site related to digital DOF, which evolved into a
generalized discussion about DOF and circles of confusion.

You could include two or three prints of your own ideas as well, and
the client may well be receptive to them, but "those that pay the
piper, call the tune"
How much to start out
in Large Format
Posted
In addition to the camera and lenses, remember additional costs such
as meter, darkcloth, and film holders. You may also need a sturdier
tripod and head. The Toyo is by most accounts a fine camera, although
somewhat limited in it's movements with shorter lenses.
<p>
Your initial lens choice should be dictated by your past experience
with lenses in other formats - choose the LF equivalent of your
favorite focal lengths.
<p>
Depending on your shooting, you may find the Polaroid back
unnecessary.
