If you are going to sell your work as a commerical photographer, the first thing you need to do is find a good professional lab and develop a working relationship with then. Now is definitely NOT the time to start learning darkroom work. There is a long learning curve before you could be able to produce anything like professional results in a home darkroon! I've been at it for 50 years and I still would no want to do the development and printing for commerical work that has real deadlines. It's ok for fine art stuff, that you might want to sell after you work hard to get it right!(posted 8600 days ago)
