1. If you look closely at In-Class Demo 1 (black background), you will see some tiny dark pink spots. These are areas that still had butter sitting on the paper which was only removed in the final running water bath. These areas will continue to darken as it gains exposure to light, although it will never go black unless developer is applied to it. To make this a fully finished stable chemigram, I could either process it developer to make those small parts go black, or process it in fixer. Once fixed, these areas may go fully white, or they may “bleach back” into more of a yellow given many hours of exposure to room light / sunlight. 
  2. For Bonus Demo 3 (color background), this time I fully immersed the print in the fixer, rather than doing the slow dipping of the “test strip” that I did in In-Class Demo 3. This is why the background is a slightly more uniform color. It’s not very common to get a perfectly uniform color across wide areas of your chemigram due to surface tension and flow of the chemistry after it’s being removed from the fixer tray. 
  3. You may also notice how the white areas of the Bonus Demo prints are a creamier white than the In-Class Demo prints. This is because the pieces of paper used for Bonus Demos were sitting out in the white light for longer than the In-Class Demos. It’s a subtle difference that you don’t always see unless comparing the two! 
  4. The black values of these chemigrams aren’t quite as dark as they could go. I think there are two reasons for this. One is that this paper is Ilford RC Satin, which tends to not appear quite as dark as Glossy or even Pearl paper. The second reason is that this developer was mixed almost a week ago, and while it was kept in a container with little oxygen, it did seem to impact the outcome a bit. I could have added a little more concentrate Paper Developer to “boost” it and see if that helped create some slightly darker values.
