Dehaze filter

Post by PhilM » Sun 24 May 2020 12:19

Dehaze filter does good job and gives interesting results.
But it is very sensitive to the cursor value and to the haze color.

It would be nice to have dehaze as an adjustment layer to be able to fine tune the dehaze later in the workflow.

I was about to say, apply it as a dynamic filter to a placeholder layer. But dehaze does not work as a dynamic filter.

IMO, usually one only needs 3 filters for enhancing pictures:
- Curves
- Dehaze
- Light/Shadow (sometimes)

What do you mean by "cursor value"?
With an approbriate size, Dehaze almost always calculate the correct color value by itself. And if it doesn't, the automatic color is a good starting point, that only has to be tweaked a bit.

Dehaze is creating a vector layer having a layer mask.

The fill color of the vector layer is the dehaze color.
Furthermore you can apply Curves to the layer mask (best as an adjustment layer) to modify the result.

So it is possible to fine tune Dehaze later on.

"IMO, usually one only needs 3 filters for enhancing pictures"
Pretty much agree.
I tend to use "Levels" and "Hue/Saturation" in place of "Curves" so I can have separate masking for each.

"What do you mean by "cursor value"?"
I meant the "Size" cursor.

"So it is possible to fine tune Dehaze later on."
Now I have a better understanding of the construction. I will try.
Still, the "Size" cursor can't be fine tuned afterword.

Thanks a lot.
