Hi all…I’m going to setup my first darkroom with the intent of producing my own separation and screen films from 35mm and 4x5 camera photography. These films will be a process step in other emulsion based media, mostly screen printing but also experimenting with etching and solar/diazo exposures. I know a lot of the below really falls into the process camera and copy camera realms of yester-cade, though I’m hoping to do this with basic darkroom equipment, knowing these are steps towards artistic experimenting rather than accurate photo duplication. And yes, the computer makes it easy these days, but I’m already strapped to one of those things in my architect world.
I’m looking for teaching and how-to resources, either discussions here, websites, used books and the like, that can help guide me through some of these older analog topics:
Color separations- I’ve uncovered a fair amount of online info related to using RGB filters to separate out primary colors. Not so much, however, on getting to the CMY separations. Is it really as easy as shooting the RGB negs? I suspect not since numerous resources describe pre-press separation as being a complicated multi-step process.
Grey component replacement- I’ve seen this phrase used for isolating blacks in a CMYK separation. Can’t find anything about how. Maybe there are other terms for this process?
Density separations- I’ve seen this mentioned a couple of times within the general topic of color separating. Can’t find much else that describes it as a darkroom procedure.
Tone separations- think I came across this within the general topic of posterizing. Can’t find much else that describes it as a darkroom procedure.
Posterization- found a good step by step and some other general descriptions. I suspect there are other processes given the wide variety of results.
Halftoning- via screen films, can’t find much technical data on how they are used with an enlarger.
Spot color separation- is this even a possibility using a traditional enlarger?
Other analog experimental processes that might fit this objective of “separating” a photo into different layers?
