Hello, new here, and new to photoshop.

If I have taken a portrait of someone and would like to offer it in several sizes (the standard sizes, 8x10, 5x7, wallets, etc) Do I have to reformat it for each size, or if I size it in 8x10 will the proportions remain the same when they are printed smaller?

Most common image sizes in the U.S. (for example, 4x6, 5x7, 8x10) have a different aspect ratio (ratio of width to height).

So, you'll want to crop the photos for the desired print sizes, unless the image is already at the desired aspect ratio. For example, most DSLR models produce an image with a 3:2 Aspect Ratio. So, that's already correct for 4x6 inch print. But, it would not be correct for a 5x7 or 8x10 inch print. It would be for an 8x12 or 16x24 inch print if offered by your printing service, though.

However, most non-DSLR models product an image with a 4:3 Aspect Ratio. So, you'd need to crop to get the right ratio of width to height for a 4x6 inch print.

Photoshop has a crop tool (a resizable, moveable box that matches the desired ratio of width to height) for that purpose. It shows you an outline of what the image will look like before applying the crop. That way, you can crop for both the desired composition and print size at the same time.
