Zdepth for basic distance fog


#1

Sorry for the noob question, but I searched and tried how to make a simple distance fog over a beauty pass in fusion using a zdepth pass, without success.
In photoshop it is very straightforward, you just put the zdepth pass on top of the beauty pass in screen mode and voila.

you could do the same in fusion

use a merge to put your Zdepth pass over your beauty (use the “apply mode” screen or “normal” with the alpha gain set to 0)

or you could use a fog node

or you could use the zPass as mask in a grading node (colorcorrect or brightness/contrast)
