Clearing Haze from Photos

These two Photoshop actions can be used to clear haze from digital photographs. Try each to see which one produces better results.


The first action is based on ideas I gained from Dan Margulis' excellent book Photoshop LAB Color: The Canyon Conundrum and Other Adventures in the Most Powerful Colorspace. Basically, it converts the image into LAB color space and then applies curves similar to the ones in Chapter 3 of Dan's book.

The second one is based on an idea from one of Robin Bourbounnais' postings on the SooCool forum. It simply creates a 75% opaque levels adjustment layer with blending mode set to soft light. Note that the levels adjustment isn't actually applying any levels adjustments; it's just a cheap way of making an adjustment layer. Nevertheless, you could tweak the effect further by playing with either the opacity or the levels adjustment.
