Print color fairly often. I lucked out when it came to graduate schools, full color and silver labs. Can get up to 30x40 on a 10x10 enlarger processed in a Hope processor.
I do as well, just depends on the image or film if I feel it's something that should be in color or not. I've been doing a lot of slides as well, either just projecting or scanning those though for the obvious reasons.
I print color only.
12x16 max in a Fujimoto CP-31. Sometimes I process smaller formats in trays.
I develop films C-41 and E-6 as well as ECN-2 cine film.
I do RA-4 color printing, from 8" to 20". Use Jobo CPE+ for film and small print and CPP2 for large print.
Have the Epson large format, but like the RA-4 better.
