1. I got lots of bubble, so much that it is impossible get rid of. I just
left them there for now since this is going to be for exposure test only.
2. About how much gelatine/water ratio do I need? The article in APR by Mike
Shorter says 28 gr. gelatine in 460 ml water. That seems a little diluted.
Another book uses 20 gr / 100 ml, which is quite thick. (I don't have the
author's name because I only have a few xerox pages, but it mentions that the
formula is based on 1938 edition of American Photography magazine). I started
with something in between, 28 gr. / 320 ml. In general, what is the effect of
the amount of gelatine to the final print?
In my first tissue, I didn't use glycerine, gum, or tween. I only added some
syrup as plasticizer.
Thanks in advance!
