| It depends on what kind of haze you are talking about, some samples might help!
But one of the best techniques is called local contrast enhancement, which is basically just an unsharp mask with settings:
Radius: 40-60
Amount: 0.10-0.20
Threshold: 0
Note: I use GIMP, not Photoshop, so the scales might be different, but the idea is to have a very large radius and a small amount, instead of the other way around which is used for normal sharpening.
Note 2: The speed of the unsharp mask operation is dependent on the radius, so be prepared to wait a minute or two! |
