Image Brightness & Contrast Adjuster - Frequently Asked Questions

How much can I brighten a dark photo?

Increase brightness up to +200% to rescue underexposed photos. Our smart algorithm prevents blown-out highlights while lifting shadow details. Works great for photos taken in dim lighting.

What's the difference between brightness and exposure?

Brightness lifts all tones evenly. Exposure mimics camera settings, affecting highlights more than shadows. Use brightness for overall lightness, exposure for correcting camera exposure errors.

Can I darken an overexposed photo?

Yes, reduce brightness down to -100% to fix washed-out photos. Our tool recovers detail in blown-out skies and overexposed faces. Combine with contrast adjustment for best results.

Should I adjust brightness or contrast first?

Adjust brightness first to set overall lightness, then fine-tune contrast to add depth. Finally, tweak saturation if colors look washed out after brightening.
