These are a few of the basic adjustments you can make if you want to venture beyond the automatic presets, filters and special effects in your photos app.
The support site for your preferred photo-editing app should have more precise details and guidelines on using these tools and others, but here are a few parting tips:
Edit your pictures in a place with neutral light and not near a bright window, which can affect how the image looks on the screen.
Take your time and explore.
Don’t worry about messing it up! In most apps, you can discard or undo your changes if you don’t like what you see.
