The bi-post contacts are for triggering the old bulbs, you might
contact Bill Cameta and see if he has the old flash guns and
reflectors. If you want negs get Polaroid P/N 55, if not get 52, but
film is cheaper (Arista 125/400) from Freestyle Sales in L.A., about
$40 per hundred and look around for another lens with a pc flash
sync.It might be a good idea for you to find someone who is willing
to teach you film developement basics, it will save you a lot of time
and trouble. There is nothing easy about film developement, if it was
there would not be so many posts here about how to do it. Pat

Sounds like you might have some serious heat fogging. Since the FP4
works well, get rid of the garbage, stick with what works. Pat

Invest a little time in research of developers or find someone's
who's work you respect who uses the film you want to use and then
pick their brain about the developer they use and how. You will spend
one to two years (depending on time invested) learning the use the
developer of your choice with all the varitions that are possible. I
have my favorites, SD-1 Pryo, PMK Pyro, and Weston's ABC Pyro. Good
Luck with your research. Pat

You might try conducting your own film speed test, and then you would
know the correct speed and procedure for your equipment. Pat

Renaissance micro-crystalline wax from Light Impressions. I live in
the desert also and it works fine. Pat

They are very good, high quality, but they no longer have a lifetime
warrenty. Pat

I would also suggest doing it on Azo single wt. paper, broader tonal
scale and easier to print through single wt. Pat

It would be a good learning experience, DO IT! Pat

I don't know what your definition of "neat stuff" is, but get hold of
Ansel's books, he use a lot of ortho film, I have used it myself and
liked it. It is not red sensitive which makes foliage light in prints
and makes for flat skys. The one thing I really liked about it was
that I could develope by inspection under a 7w red safelight or a 15w
up higher. You might want to try using PMK Pyro as a developer and
you could use Gordon Hutchins starting times for Tri-X. Pat

The Speed Grafic and the Graphflex are two different camera's, and
while I have never owned a Graphflex, I do have a Speed Graphic and a
23 holder and a 22 holder both of which fit correctly when the
groundglass back is remove and locked into position with the sliding
locks. Maybe someone out there has a Graphflex and could measure the
back for you. Pat

I agree with Ellis, Hurrell's photo's were more than pretty faces &
clothes, though that helped alot. You should go back and study his
techniques of posing and lighting and don't forget the makeup.
Remember that his were "Glamour" shots, not just someone in period
clothes. I did like the first lady in Portraits 1 (top left) looking
at the screen. Pat

With that many pinholes I would opt for a new bellows. Then you won't
have to worry for years or lose a good neg. Pat

Try the Ron Wisner site. Pat

You could try using an albumen coating as a base for the light
emulsion, it is much easier to coat with and a lot less trouble than
other coatings. Check the Albumen & Salted Paper book, also the
Keepers of Light book. If you can't find them contact me and I will
look it up for you, which will include a receipt for custard (give
you something to do with the yokes) Hope you have time and patience.

You can use any size lens you wish if you are willing to move your
tripod so that your subject fills the viewing screen in the manner
you desire. Pat

Photography on Bald Mountain should be able to repair your shutter.

Your bellows draw is 12.7 inches, for a 1:1 inlargement you would
need a lens not longer than 160mm, so unless you plan on using an
extended lens board your 150mm is about your limit. Pat

To my knowledge DOF is determined by focal length, lens stop, the
distance from the lens to the point focused on and the size of the
circle of confusion, and the depth is greater with shorter focal
lenght lens than a longer one. Shutter speed has nothing to do with
DOF. This is according to Vol.1 of the Navy traing manuel 1944 Ed. Pat

I use a 75w Plant Gro bulb (ultra violet) in a 11 inch brushed
alumniun reflector and the paper under a 11x14 sheet of 1/4 inch
plate glass to contact print on Azo and develope in Pechham's Amidol
which will keep for 2 weeks in a sealed container. I adjust my
exposure so that I can develope for 5:00 with contineous brush
agitation, there is a depth to the prints that cannot be achieved
with just 2-3 minutes of development. Pat

Bruce Barnbaum in his book Art of Photography suggests 1:150 for
10:00 @ 68-F for 45 film rated at 25 ASA. I would suggest that you
get hold of the book, it is informative. Pat

I agree with Kevin, I own a Soligor digital spot modified by Zone VI
the Zone VI meters cannot be beat. Pat
-
I don't know about 45 techpan in Rodinal, since I use PMK or SD-1,
but a few years back when I use to do a lot of 35mm I used Rodinal
1:150 and it was very good I don't rememer the times though. I would
start at 10:00 and adjust from there. Pat
-
Like Cesar said, if bellows draw and subject to film plane distance
is not a factor then you should be able to use either lens. Pat

Check the Shutterbug! Pat
Just got a Shen Hao 4x5
in Large Format

I can/would buy a used Zone VI for a lot less than $1000 and get a
lot better camera from what you are saying. Pat
