At first I was a bit scared about the film grain, which is amplified because I have a standard scanner not a film negative scanner. However, a bit of Photoshop massaging, and voila. If I had a proper film negative scanner I reckon there will be appropriate film grain without too much "digital scan" grain.
(The Camaro picture has a bit too much digital grain though, unfortunately... Hmm...)
