Frequently Asked Questions
What is the difference between brightness and contrast?
Brightness adjusts the overall lightness of every pixel uniformly. Contrast adjusts the difference between light and dark areas — high contrast makes darks darker and lights lighter.
Can this fix a completely overexposed photo?
Reducing brightness and contrast can recover detail in mildly overexposed areas, but completely blown-out pixels (pure white) contain no recoverable data.
