Reveal the True Colors of the Deep

AI-powered color correction for underwater photography. Instant results, zero quality loss.

Red dies at five metres

Water absorbs light wavelength by wavelength, starting with the longest. This is not your camera failing: by the time you press the shutter, those colours are already gone.

Below that, only blue and green are left. Correcting means giving each pixel back what the water took — which is why the depth of the shot changes everything.

This is not a filter

An underwater photo is not short of contrast: it is short of wavelengths. CoralIA estimates what the water absorbed — depth, water type, lighting — then reconstructs the inverse curve for that particular image.

The result is a 3D lookup table, applied to your photo at full resolution with no recompression. You set how strongly it applies, and every manual adjustment stays yours.

Your photo is sent to our servers in Europe for analysis, processed in memory and never stored; only the correction table comes back, and it is applied in your browser. No trackers, no analytics.
