Optimum image size from a subcompact...?

[Jim Duda]

There are several Image Size choices from my 10 MP point and shoot... 3648x2736 / 2592x1944 / 2048x1536 / 640x480 / (3:2) 3648x2432

When is the 3:2 choice preferred? Should I choose this if I know the picture will be printed as 4 X 6?

(Since most of my stuff is sent to friends via e-mail, I probably would choose 2048 X 1536 and re-size to 800 X 600 in Photoshop.)

i dont know about other people in here, but i always shoot at the largest my camera can go.. then if i'm printing a 4x6 i crop to that size

There is no reason to not shoot at the maximum file size. When you shoot at a smaller size you are effectively shooting at a smaller pixel size, and thus not grabbing as much detail which limits your ability to crop later.

Thanks...understood about shooting at max file size.

Is there not a "technical reason" for the 3:2 format choice...or is that just marketing and a pretty much useless option?
