Not a question about digital, per se, but a question on how to relate the digital thing which I know fairly well to the analog thing I want to learn. I've been studying split grade printing and have experimented with it a couple-few times. Now, I want to wrap my brain around it and start using it for real. There's always some relationship between the way Photoshop works and the way real photography works. Since I know the digital, it make sense to me to work backwards and put what I understand into context in the darkroom. So, it seems to me that split grade printing in the darkroom has some similarities in Photoshop. Let's say I have scanned a black and white negative into my computer and I am editing it digitally. One of the first things I do is go to the IMAGE > ADJUSTMENTS > SHADOW/HIGHLIGHT control then expand/contract my shadows and my highlights to make the overall contrast of the picture the way I want. In the darkroom, using split grade, I would print either the shadows or the highlights the way I want them to look then make a second exposure to burn in the highlights or the shadows the way I want. (Either start with the shadows first or the highlights first then work up the other.) One of the problems that you can encounter with single grade contrast printing is that you can end up on a merry-go-round where you fix the exposure the way you want then, when you go to tweak the contrast and you have to reset your exposure. Around and around you go. I got off that merry-go-round in the digital world by using the Shadow/Highlight control. It seems to me that split grade printing would get me out of that same vicious cycle in the darkroom as well. Am I on the right track or am I just spinning in the sand?
