Re: Dave Soemarko's LC-1B
Sandy,
Ortho Lith film can be addictive, Ultrafine online has .007 thick lith
film here: http://www.ultrafineonline.com/ulhicoorlifi.html. I use their
contone dupe film in camera a great deal, and it's cost effective as well.

Just want to thank Dave Soemarko for his LC-1B formula, which I just
used for the first time this evening in an attempt to do some BTZS
type testing with a Kodak Ortho lith film. I had forgotten about this
formula and did some initial tests with various other formulas, with
very bad results.
Then I remembered Dave's work on the formula that was published in
Post Factory, and in the book by Christopher James. So I went to
James, got the formula and mixed up the soup. It really worked great.
You have to really test this lith film carefully because it is trigger
happy in terms of contrast, but with a bit of work I was able to
derive data that should allow me to expose the film in the field over
a fairly wide range of SB R and develop for continuous tone.
I might mention that the immediate reason for this testing lies in the
fact that I just took delivery on a new Richard Ritter 20X24" camera.
Very rigid, with a full range of movements, and weighs 23 lbs! I have
some continuous tone film on hand but at the current price I thought
it might be interesting to get used to the camera with lith film,
which is much less expensive. And as luck would have it, I have a
couple hundred sheets of Kodak Ortho lith film, so that is what I am
experimenting with. With the very good success I have had with the
Soemarko LC-1B formula I figure in a day or two I will be ready to
load the new featherweight camera in the SUV and hit the trails.
BTW, if anyone is interested in seeing pictures of the feather weight
20X24, go here,

Also note the round photography in the background of all three
pictures. That photograph is a portrait of me made by the famous
photographer Sam Wang.
