If I’m shooting with film and it’s a subject that I am comfortable with 1-2 frames. Something less comfortable 3-5 frames.
If I’m shooting digital, I’ll go till I like what I see on the LCD and then take 2 more.
It’s not that I don’t like using a lot of film, I just feel that when I use film, I am doing “real” photography and I think about the image a lot more (composition, viewing from multiple angles etc) before I make an exposure. My 1-2 frames on film will probably take longer for me to shoot then 15-20 on digital
