Asked on a forum today: "When resizing your photos for print, do you use the Crop Tool or the Image Size function?"
Cropping is unnecessary if you've composed your image
exactly right in camera,
AND you've chosen a 2:3 print size that matches your camera's sensor shape - eg 6x4, 6x9, 8x12, etc. But it's pretty rare that both of those factors align for you, so it's common to have to crop for print, either for composition, or print shape, or both.
There are several schools of thought on this ...
1. Don't crop, don't resize, don't do anything
This can apply if you upload to your lab via ROES or similar, which allows you to choose the crop while uploading. This is undoubtedly the easiest way, but you can't accurately sharpen your images if you do it this way; so if sharpening is important to you, avoid this method. (
The case for resampling)
Obviously, this method requires neither the Crop Tool nor the Image Size dialog.
