Lately I experimented more with ratios of chemical. Still I have not been able to judge which of the ratios is better. I used both cold pressed and hot pressed paper for the experiments. The ratio are 1: 1 and 1:2 of potassium dichromate to gum solution.
The next experiment was with hard pressed paper. Though in the 1:1 ratio of hard pressed, I went further to double expose it. I should have done double exposure with 1:2 ratio print to get a better understanding. I should probably do that in my next experiment.
And then I put 1:2 , 1:1 ratio on the same paper and exposed them in UV light for 8 min. 1:2 ratio paint on left and 1:1 ratio paint on the right.
