This may be the dumbest question ever asked here. 
I basically want to constrain some of my crops to keep them the same as what comes in from my camera, which is a 4:3 aspect ratio.
Does constraining the crop really just constrain the crop, or does it actually resize the image?
The reason I ask: Within the Constrain options, there is a 4:3 Book and a 4:3 DVD. Does it matter which one I use? I mean, 4:3 is 4:3, right? I realize that the default selection is different, but I'm going to re-size anyway. I don't want this thing shrinking my 8-10 MP images just because I want to maintain an aspect ratio.
Thanks.
