Even back when I made some good spending money shooting weddings and the like I only really needed to push a few times. Now, a night football shooter might do it 100% of the time just to try to cut down motion blur, but for me it was more playing around then anything. I did like Diafine/Tri-X, but really don't know if that was considered "pushing" or not. If I really need speed now I grab my Canon 5D and fast lens. Opp! Sorry about that, but it just the facts. Right now I'm stuck around ISO 100 and can't seem to move the ASA/ISO dial. I just never thought you got the best out of your materials by pushing. JohnW
