Re: Lith film thickness was Re: Dave Soemarko's LC-1B

I might also add that the Continuous Tone Dupe film is the easiest to get your head around exposing and developing, as DBI in Dektol and exposing at an EI of about 6 is all you need to remember.

Hi all
Can anyone tell me the thickness of regular panchromatic film? How floppy, for want of a better word, (maybe practical?), is 0.004mm film in 8x10 inch size?

I have been using Arista Premium Halftone Supreme from Freestyle
for making my enlarged negatives. I wasn't aware of the Ultralfine
until now. Has anyone compared the two? The thicker base is
appealing (.007 ml. instead of Arista's .004 ml.)
thanks Erie.

    Ortho Lith film can be addictive, Ultrafine online has .007 thick

    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.
