First, let’s dispel the notion that commercial photographers have a camera in their hands every day. This will vary for individuals, and by season, but I would guess that I spend a good 75-80% of my working hours in front of a computer – not out shooting. I consider that to be a pretty successful ratio. No one starting out really thinks about it, but digital workflow, retouching, billing, marketing, pre-production, post-production, accounting, taxes, etc… and the plethora of general business paperwork takes up a ton of time.
