Frequently Asked Questions — Image Brightness & Contrast
What does brightness do?
Brightness adds or subtracts light from every pixel equally, making the entire image lighter or darker.
Brightness vs contrast?
Brightness shifts all values uniformly. Contrast increases the difference between light and dark areas.
Can I adjust multiple settings?
