Local contrast can help give images more descriptive and well balanced tones. What you’re doing is making a vague/blurred version of the image; using that to lighten/darken the image underneath; then inverting the effect.

So light areas get darker, and dark areas get lighter, but with this kind of area-based effect. Similar to what you can do with Unsharp mask, and you can try it with different blur modes too, like surface blur.

Layers from bottom to top:
– Original picture
– Copy of the original -> Filter (Convert for Smart Filters); Gaussian Blur set to something high. Set this layer to Overlay. (This will put more light in the dark areas, to bring detail out in shadows)
– Clip an Invert filter to it
– Then another copy of the original image with Linear Light blending, and a low opacity. (This brings the contrast back)
– Curves layer set to Color blending with a flat RGB curve. (But a desat layer or just a white Solid Color set to Color would work the same)
