How To Dehaze and Color Correct In Photoshop

Haze, unfortunately, is something that we all occasionally have to overcome. It can be caused by a light fog or mist and even with fine showers that mix with ambient lighting to soften your image and add an unwanted color hue. Often you can find a good subject to take a photo of and not see any haze with the naked eye, but your camera will produce a hazy image. This is because haze can also hide in the ultra-violet spectrum, which we can’t see. There’s no need to discard those images anymore. We can dehaze and color correct with ease by following this quick tutorial.

This example image

The photo we have used in this tutorial to dehaze and color correct was taken on a very dark and wet night. I was on the south side of the banks of the River Tyne with the Castle on the north side approximately 400 meters away. Because of the relentless fine rain and the ambient light which was added to by the stadium lights behind the castle. The image came out very hazy and with a green hue, I was happy with the composition so I sought to try to remove the translucent haze that had been caused by elements. This is how I did it.


Step-By-Step Guide to Dehaze and Color Correct

1. First duplicate the Base Layer and then hide it so we are working with the copy.

4. Do the opposite, grab the point in the upper right corner and drag it left to brighten the highlights.

5. Because our haze has a green hue, we will select the Green channel to adjust first.

7. Click and hold on an area that has a strong green hue in the highlights and drag down to lower the green saturation.

8. Now do the same in an area that has a strong green hue in the shadows.

9. Repeat the same process with the Red Channel.

I wanted to increase the reds in the highlights of the castle so I dragged my cursor up in that area.

10. Repeat the same process with the Blue Channel.

Like with the reds adjustment, I increased the blue saturation in the sky by dragging upwards in that area.

11. You can see all the adjustments when you go back to RGB. Notice how all the curves now follow different paths.
