The difference between a good photo and a great one might be the few minutes you spend editing it before you share it. These techniques can quickly boost the quality of your photos.
You can make all of these edits on a smartphone using built-in tools, like Apple’s Photos app or Google Photos. There are, of course, more in-depth apps available for both hobbyists and professionals.
Recover Details From Shadows and Highlights
Highlights are the lightest areas of your image, while shadows are the darkest. If either of these are pure white or pure black, these areas are over- or underexposed. Fortunately, you can try and claw back some detail from these areas using the “Highlights” and “Shadows” sliders.

The format you used to capture your image will affect how much detail you can recover. If you shot an image in RAW on a digital SLR or mirrorless camera, or you have a smartphone app that can capture RAW photographs, you’ll have a lot more to work with.
However, if you’re using a compressed image format, like JPEG, much of the detail in the highlights and shadows is discarded during the compression process. A RAW file is much larger because it retains all of the data captured when you press the shutter, including portions that are invisible to the human eye without some editing.
