A little grain in film photos doesn't hurt, but there is such a thing as overkill. Recently I shot a roll of Illford Delta 400 black and white film. The finished product I wasn't excited about. Typically when I shoot film I bump up my ISO to 800 to make the shutter speed faster. It may not be a good idea to do that with this particular Illford film. I found many of the photos I made too grainy. Based on the amount of grain, I am thinking the film may be too grainy even shot at ISO 400. I'm undecided if I'll give it a second change.
The image above was shot in Asheville, NC on Eagle St. I think it turned out pretty good. Thanks for viewing.
