Frequently Asked Questions
What is histogram equalization?
Method to enhance contrast by redistributing pixel intensities.

For underexposed, overexposed, or flat-looking images.

How histogram equalization works
Histogram equalization analyzes the distribution of pixel brightness values and remaps them across a broader tonal range. This can make details more visible in images where brightness values are concentrated in a narrow range.
Browser-based processing
The effect is generated with browser image and Canvas processing. No separate server conversion step is used for the visual effect itself.
What the effect changes
Histogram equalization redistributes existing tonal values; it does not reconstruct missing detail or guarantee an improvement for every image.
Tips for better results
Start with a clear source image and use moderate settings before increasing the effect. Compare the preview with the original because stronger processing can intentionally reduce or exaggerate visible detail.
