Thread: grade

    grade

    I got a 30x40 camera and want to shoot glass plates.
    For testing the camera I made some shots on paper to check for proper focus and lightleaks etc.
    I used paper graded 3 and together with the Symmar lens the results are much to harsh. As next step I wanted to try some premixed emulsion like liquid light which is also graded 3, but now I am not sure how to get more grey into the images.
    Is there a possibility to mix the emulsion with gelatine or something to get grade 2 or 1 or can I use some filter on the lens to lower contrast?
    Thanks and and Regards

    I have never tried paper negatives, but I would use resin-coated variable contrast paper and use a yellow filter on the camera lens. Yellow light will reduce the contrast on VC papers.
    A soft working developer would be useful as well, like Kodak Selectol-Soft.

    I'm sure there was once a manufacturer of variable contrast liquid emulsions which may have been suitable for coating on glass, but I can not remember who?

    Thanks for your answer, I found different suppliers for the liquid emulsion, I will start a try with a yellow filter.

    Try preflashing the paper, that softens the contrast.
