Hi, I'm a hobbyist who has been asked to shoot for a friend's wedding (not the main photographer, of course). For personal work (mostly 35mm format), I normally try to use the entire frame. However, I know that when couples asked for prints, they also want them in sizes other than that similar to the negative aspect ratio (e.g. 5x7, 8x10, etc). Hence, I would like to ask the pros on the list how much do you crop at the viewfinder (especially for candid/pj type shots). TIA.
