Im never going to use a film camera at a gig because I'll usually knock out the best part of 1000 shots in a night- that would be pretty expensive on film!
However I just went on holiday and, along with a compact digital, brought a 40 year-old Nikkormat and some film- the results were awesome. Shots which looked garbage on my compact, when taken on film took on a new life, and I cant put my finger on why!! You stop and think before firing the shutter
People think the expense involved in using film should make it redundant but I basically shelled out £30 in total. Not a bad price to enjoy a weeks photography while on my hols!!
PS. I'll bet anything that no Digital SLR will still be functioning after 40 years!
