Anyone ever try developing a negative (or roll) in multiple developers? Like a two-solution or divided developer process, but with two different developers instead of a single divided developer or developer + alkali etc. I'm not a chemist so this might just be crazy talk but figured I'd ask. For example, suppose you're shooting 35mm Delta 100, and you want the film speed of say DDX, but the super fine grain of stock Perceptol. Could you use DDX first, at a higher concentration (maybe 1+2), agitate for 1 minute, then let it stand for a short time , maybe 1 minute (so total two minutes so far to get full development of zones I-II), then a water rinse (or stop bath followed by water rinse), then pour in Perceptol 1+0 and continue development until the highlights are wherever you want them. I guess my "reasoning" here is since relatively little silver is deposited in the low zones the possible increase in grain from using a highly active DDX solution won't be apparent in the print, while at the same time almost all of the mid to high value development is by Perceptol, yielding extremely fine grain. Obviously testing would be required to establish smooth gradation etc. Is there any merit to this?
