I meant to ask how many shoot large format film commercially?
I do.

Would a potential client be turned off if they knew I/You shot film only?
No. If so, they didn't tell me, and I didn't care.

Question:

If a client wants my style, why should he be turned off if he knows I'm shooting film? Is film bad? Does film have less value? Does it have viruses? Does it cause heart attacks? Does it make you fat?

Oh, sure, film doesn't have as much hype as digital (whatever digital might mean to the dumb people out there).
