Today I was able to make only two prints because weather changed. One sheet was covered with emulsion in the mornig to check discoloration during long drying (about 6 hours) and the second was covered 2 hours before exposure. The thing is that there was no discoloration whatsoever on the first emulsion. Last time I observed a slight change in color towards lime. Both sheets were exposed for 6 minutes and there is a small difference in exposure – longer dried sheet is a litte bit overexposed (darker).
More tests will be conducted with stable lighting source in June and afterwards.
It’s so fun to play with this technique! :)
