Some adjustment for color. There are some reds represented and some greens. This is like a 60's science film strip

Further experiments with CD-2 TSP and Ascorbic Acid. I turned down the TSP to 3.6 grams / 250ml (14.4g/l). Jacobsen 1942 says a 2% solution of TSP should be approx pH 0f 10 (my memory isn't precise) but 2% would be 5 grams in 250ml. 5 Grams continues to give me a reading over 12 right down to 1gm/250ml . I didn't break that until I got to 0.5g in 250ml when if finally dropped around pH 9. That could be my tap water however that pH is around 7-8.... The Ascorbic Acid brought the pH back down to around 4 and it took almost 3gm of TSP to bring the pH back up to 10/10.5. The CD-2 did not react when mixed in water, no magenta coloration. I used that anyway, afterwards feeling my container or stirrer was contaminated because a later test showed the CD-2 going deep magenta in water. I assume this contamination of the CD2 is why we get no real color in these pictures. However, finally, the emulsion remains on the base and we have images. I have a frame or 2 left on this strip that I can retry with a fresh developer. However weird this is, we finally have pictures, with literally 3 ingredients and they may even be color
