What does increasing contrast do?

Higher contrast makes light areas lighter and dark areas darker, creating a more dramatic, punchy look. Lower contrast makes the image look flatter and more faded.

Can I fix a photo that is too dark?

Yes. Increase the brightness slider to lighten the overall image. Also try increasing contrast slightly to restore shadow detail.

Will adjusting brightness change the image dimensions?

No. Brightness and contrast adjustments only affect pixel color values. The image size and dimensions are not changed.

Is there a way to automatically fix brightness and contrast?

The Auto Enhance option (if available) automatically calculates the best brightness and contrast values based on the image histogram.
