Frequently asked questions
When should I increase contrast?
Flat, hazy photos often look better with a moderate contrast boost, which restores depth and separation between tones.
Can too much contrast ruin a photo?
Yes, extreme contrast crushes shadows and blows out highlights. Start small and preview, then back off if detail disappears.
Does contrast adjustment affect file size?
It re-encodes the image, so file size shifts slightly, but pixels and resolution stay the same. Lossless formats like PNG keep quality.
