How to edit pictures using Photos on a Mac

Photo-editing applications can be intimidating, especially if you don’t use them often. But with the tools available in the Photos app on Mac, making adjustments and corrections to improve photos is much easier than you might realize.

With options to correct red-eye and remove marks, you can fix minor blemishes, as well as crop, straighten, or rotate a photo. If you’d like to go further, you can adjust the white balance, light, and color to enhance your picture. And best of all, many of these tools have an Auto feature that makes the improvements for you.

Prepare your photo for editing

Before you start making changes to your picture, you may want to make a copy of it. This allows you to hold onto the original, because all changes you make will be saved and then appear on all devices where you sync the Photos app.

Step 1: If the image was taken on your iPhone or iPad and synced with your Mac, you may need to import it first. Right-click the photo and choose Import. Then, head to the Imports section of the sidebar to select the photo.

Step 2: To copy the image, right-click the photo or select Image from the menu bar and choose Duplicate 1 photo.

Step 3: You can then make adjustments to the copy if you’d rather keep the original image as is.

Use Photos to edit the image

To open the editing tools in Photos, either select the image and press Return or double-click the image and choose Edit in the toolbar. Your photo will open in a separate window.

Zoom: On the top left of the toolbar, you can use the slider to zoom in on the photo if needed. This is handy when using certain tools like Retouch and Red-Eye.

Auto Enhance: If you’d like to let the Photos app automatically improve the entire photo, you can use the Auto Enhance feature. Select the button in the toolbar that looks like a magic wand to enable Auto Enhance. To remove those enhancements, deselect the button.

You also have the option to use Auto Enhance for individual elements, which we’ll describe below.

Step 4: Many of the tools also offer an individual Auto Enhance option. If you prefer to have Photos automatically improve specific elements rather than the entire photo, choose Auto to the right of the tool.
