There is still more you can do to enhance the looks of each photo for your screen, especially if it's darker than you want it, or not quite as colorful: Susette Horspool, CC-BY-SA 3.5 3-Editing Photos to Look Good on the Desktop Here is a screenshot of the Photos editor, after you've clicked on "Crop." Here I will check to make sure the fence post is straight, resize the photo to 3x5", and make the frame smaller, if I want to zoom in on particular features. It will also move another edge to keep the 3x5 shape, so you might have to adjust the photo's position again.

However, it also gives you the means for modifying both of those changes. It may also rotate the photo slightly, if it doesn't think it's straight. The computer will automatically reshape your photo to that size, but it does it by cutting off part of the photo. Click on "3:5" near the bottom of the list.
