Do you still use Film? Yes (APUG is the ANALOG Photography Users Group)

Do you Develope your own? Yes - B&W which is my primary film medium

What are the advantages/disadvantages of Digital and Film?
Digital may provide faster results; shorter workflow to the web or other e-media - and cheaper per shot after surviving the initial gear purchase
Film, especially B&W, is more easily archived, offers higher affordable resolution, and to me, a more interesting workflow

Can you, do you use both? Yes

Do you use Film then scan the negs before printing?
Not generally, as my serious prints are optical on gelatin silver paper

Do you think that film offers more chance of producing art by mistake / happy accident?
Hmmm - that could be a real bag of worms, but my gut sense is yes, although I try to be precise and consistent which would reduce that likelihood.

Have you any other thoughts as to why film feels different/worse/better/more precise / clumsier?
Many of the differences I feel are due more to the equipment I use than the medium. My digi-stuff is relatively recent, with full and exotic automatic capabilities, most of my film shooting is done with older, fully manual cameras - or at most auto-exposure. Work with the latter tends to lead to a slower, more thoughtful approach to my photography

Hope that helps.
