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. If there's too much of an edge showing, you can click and hold that edge of the photo to move it in.

To reformat what shows in the photo, click and hold in the photo somewhere, then move it around within the 3x5 shape, until all the elements you want to be included are showing.

Click and hold to grab the scale, then move your mouse (the scale) up or down until the key lines in the photo are straight.

If you want to straighten the photo yourself, go to the scale just to the right of the photo.

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.

On the right hand side, you'll see a number of choices.From the tabs in the middle of the screen, click 'Crop.' Now you can change the looks and shape of the photo.In the upper right hand corner, click 'Edit.' Choose one of the photos on your temporary 'house' page.
