Almost 30 years ago I had my own photo studio and did portraits, portfolios and commercial photography. Now that I am fifty I am considering going back into business doing basically the same kind of photography again. I am tired of working for someone else and I want more job security. The question is this. I know that I will need something more than my 35mm camera to do this right but I don't know if I should go with a traditional film based camera like a Hasselblad or Mamiya or should I go for a digital camera? I want to be able to offer at least 16x20 portraits, but most of what I will sell will be 8x10s.
