First, I am retired but shoot images almost every day..
If I was a pro, it would mainly be digital..
I love digital for color with small toy cameras.
I super enjoy BW film in my Leica M's, less SLR, Nikon-Canon-Pentax..
Develop in kitchen and scan on Canonscan with XP (off line).
If i was Pro, no way pay Leica prices as profit is major rule.
Digital in Nikon-Canon..whatever.
I have done occasional pro work using digitals that nobody here would consider..
The quest for super monster MP and lenses size of Bazookas is almost funny.
Yes I have made huge prints( from 35mm and 6x6) .
Go simple, have fun even as pro work..
