Hello, Last night I posted a question about the ratio of exposure between an aquatint screen and a photographic image on solarplate. I was unsure of the ratio to get good tonal range. Today I struck an even bigger problem though. It was a very overcast day.(I am is Napier, NZ..very harshly sunny place!) I ended up doing a 30 min exposure for the aquatint screen and a 30 min exposure for my image. STILL the densest areas of the image did not expose long enough to harden the solarplate. I was left with a plate that had good details in the highlights and midtones...and a big gooey mess in the shadows What confuses me is that I had exposures of 4 min with the aquatint screen on a brighter day that were successful. I have trouble shooted and I am sure I have eliminated the most obvious things. My transparencies were definitely emulsion side down for a start. Any ideas? Anyone?! It is an expensive material for me to experiment with on y art student budget but I am determined to figure it out!
