Gradation curves adjustment: key for showing blow outs


Recommended Posts

It would be very helpful to have a feature working with gradation curves: in photoshop, you can press a key and then the programm will show you pixels that are fully saturated (at the high or low end of brightness) as you modify the gradation curve. This is very helpful for example to brighten an image up without blowing up some pixels (saturation).

Gradation curves? I looked that up and only found a term used in printing. If you mean just your bog standard curve, I don't think that clipping warnings are necessary for this, given that it entails adjusting points on a histogram graph.

Given that people have requested clipping warnings for the Photo Persona since at least 2017, you are not alone, but it would seem to indicate that it is unlikely to be added.

There is a warning available in the Levels adjustment, although it requires dragging the sliders while holding ⌥. If it worked while clicking on the sliders, it would be more accessible.

There is also a workaround entailing procedural texture, though I have not tried it.
