Generally this tool brightens up an image, smooths out shadows and highlights, makes a more ideal contrast, and just generally makes things look clearer. You can stop it at any point along the axis. The “Enhance your photo” tool is an all-in-one slider: click and drag the slider from left to right to apply automatically-selected filters to “enhance” the image, according to the Photo app. Right below the Crop button are two tabs, “Enhance” and “Adjust.” Let’s look at Enhance first. When you’re finished, click “Done” to return to the full Edit interface. To get a non-square rotation, click the circle beside the right-hand menu and slide it up or down. The “Flip” button will flip the image horizontally, but not vertically, and the “Rotate” button will spin it clockwise by 90 degrees.

This is quite useful if you want your image to be viewed on semi-standardized devices, like a smartphone or TV (16:9), iPad (4:3), or a corporate projector (usually 4:3 as well). You can click and drag the circles on the corner to manually select a cropping box, or click the “Aspect ratio” button to choose a standard size. Click it to open a dedicated cropping UI. The “Crop and rotate” button is the most prominent tool, as it’s visible at all times.
