Highlight recovery test

Overexposed pixels can sometimes be recovered. This happens when at least one of the channels (red green or blue) is not overexposed and can be used to guess what kind of details should there be visible. The most complicated (and usually impossible) part is finding the right color (therefore most of the highlight recovery algorithms give monochrome results).

What we are looking at?

The default view shows the image without any post processing (no denoising, sharpening or other tools). White balance was set manually on the lower, right-hand rectangle at the grey card. If possible 25% and 100% power was used, if highlight recovery is combined with EV compensation -0.5 EV and -2.0 EV was used, optimum settings were chosen if else.
