FAQs
Can I fix overexposed photos?
Partially — lose detail in pure white pixels. Better to expose correctly when shooting.
What about saturation?
This tool: brightness + contrast only. For saturation/colors, use full photo editor (Photoshop, GIMP, Photopea).
Best order?
Brightness first, contrast second. Or use levels/curves in advanced editors for finer control.
