I'm going to disagree, in a way, with several posters. There IS a magic bullet, and you already have it. It's called film and a darkroom. There's NOTHING like it. I call it a magical place where neat things happen.
1. Be consistant; if you develop one print for 45 seconds, and another for 90, you're going to have problems. Pick a print developing time - I use 2 minutes - and develop every print for that time.
2. Take notes. There's nothing more frustrating than looking at 2 or 3 prints from the same negative and not remembering what you did to get different results.
3. Hang out here on APUG - there's so much knowledge here, freely given.
