a friend shot a photo and the specs are as follows: width 3504 pixels height 2336 pixels 48.667 inches 32.444 inches 72 pixels/inch how do i crop/convert this landscape photo to a portrait 8x10? normally what i would do is create an 8x10 canvas in photoshop with the same resolution, shrink down original and then cut and paste into. but my resolutions are typically 180 or 300 pixels/inch. how do i make sure i get a "high res" 8x10 from the original? thanks!
