Photos
Edit images with Photos on your iPad
It may not be the most fully featured photo editor, but Photos on iPadOS is very good at handling the basics
While there are other image editing apps on iPad that leave it for dust, Apple’s Photos app remains a convenient and easy to use solution to common photo problems such as underexposure, poor composition, or the red-eye effect.
There are a decent number of tools in Photos, from manual adjustments across the whole image to one-shot filters that provide a particular look. What you can’t do is make selections or create layers – Apple leaves these to other developers these days.
