I've recently dived into color printing and the RA-4 process. I'm using a Philips PCS-150 additive color enlarger. I'm enlarging onto Kodak Supra Endura and processing using Kodak chemistry at room temperature in cibachrome drums. I did my first test strip yeterday which was a disaster because I found out that its very difficult to identify which side of the paper is the emulsion side in the pitch black. I processed it upside down and got a very splotchy print. I made my second atttempt today with much better results. I figured out a way to diferentiate between the two sides of the paper and I've got my paper to come out nicely developed and bleached with one big problem; they're monochromatic. This is really a troubling thing to me as I can't see why it's happening. I set the dials on my enlarger to the reccomended filter pack (0c 55m 65y) and my first print came out purple. I checked my enlarger head and found a loose connection but my next print came out orange. I'm not sure what's going on here but I was hoping someone might be able to offer some advice. Is my color balance really that off? It doesn't seem possible to me but I guess it could be. I'll try checking it with a color meter we have sitting around. The only other thing I could think of would be the way I mixed my chemicals, I didn't use starter for the developer because everyone on here said not to. Would my measurements not being perfect cause these kinds of problems? I only mixed 1 liter from the 10 liter kit. I hope I can figure this out, as I'd really like to make my own color prints. Here is my latest attempt. I apologize for the spots, those are from dust and splotches on the scanner.
