I got called out of the darkroom for a minor crisis and left a lith test strip in the developer. When I got back, that test strip looked kinda interesting.
This Foma 131 print was solarized in Rollei Vintage, with a 60 watt bulb held about 18 inches above the tray. Because the developer was so dilute (and getting exhauted), it took 10 minutes for the print to reach this colour. I was able to watch it gradually darken. If I try this again, I'd pick a negative without such a large dark area, and/or start solarizing before the blacks get very infected (what would be the correct term?) Anyone else ever tried this? It was an interesting experiment, and I'll add it to my bag of tricks.
