Hello, I just finished taking a black and white darkroom photography class in college to fulfill my fine arts credit. I was really good at it and enjoyed it so much that I had pretty much given up my digital camera for b/w film. Anyway, the class ended and I wanted to continue developing my own pictures so I went on craigslist and bought someone's enlarger, lens, trays, etc. I went out and purchased identical chemicals to what I used at school. I am having the following extremely frustrating problems and I don't know how to fix them: My pictures printed at home look milky, flat, not sharp, and lack detail. At school, my pictures had an almost 3-d, tack sharp, exhibition quality to them. The school enlarger was a Beseler 23CIII and mine is an Omega B66. Does this make a difference? I was usually using a #3 ilford filter at school. At home, my enlarger came with a System 7 kit and I am using the #3 as well. It seems that if I want highlight detail on my enlarger at home, I have to lengthen the time of enlargement to the point that the image is too dark overall. Some of my exposures that were 10 seconds at school are taking me 2 minutes with the same exact negative at home. Please help!!! I found darkroom photography really relaxing and enjoyable at school and would like to return to that feeling.
