No, just your broad ranging knowledge on photomaterials, color and photography gave me the idea that you may have some thoughts on this matter. That is all. I have no evidence either way except your posts.
Congratulations! Keep up the good work, I would offer to help you, but I have no clue after basic chemistry.
I need a solution to my problem of the dye being too soluble. I thought alum would work, but it did not. I guess I have to try calcium next.
Well, it looked better wet!
Here is the image that I got of the Stouffer step wedge. After scanning in the image I could clearly see both a negative yellow brown image and a positive dye image. I tried treating the brown area today and could do nothing to remove it.
The blemishes are due to the acid causing the gelatin to swell in a bubble and then burst. The spots appear to be due to dye washing out or being retained in some of the areas.
I can play with this in PS and get just about any enhancement to show more detail, better color, or even the dual neg-pos images, but this is the raw data.
As the title says, "don't laugh". Because then I would ask you to try it and see how you did on your first attempt! ;)
