Hey Rob;
wOw --- I utterly ADORE that grain in the first image, right up my street, awesome capture and talent. Imagine that as a 30"x20" sized wall print, brilliant!!!
I used to shoot Kodak T-Max 3200 asa in 35mm format years ago, then push it a stop to 6400 asa, the developing time alone from memory was 18 minutes, loved it! I love my grain, it doesn't make you a bad person.
