The Dehaze slider in Lightroom restores contrast and color to scenes washed out by fog, mist or distant atmospheric haze. Small positive moves usually look best, and local adjustments let you treat only the hazy parts of the frame. Here is a simple workflow you can adapt to your own landscapes.

How to Use Dehaze in Lightroom for Hazy Landscape Photos

What Dehaze Actually Does

Dehaze adds contrast and color depth based on how much haze the software detects. Moving the slider right removes haze, while moving it left adds a soft, misty look. It affects contrast, saturation and exposure together, so it behaves differently from a plain contrast slider.

  • Positive values deepen shadows and boost color.
  • Negative values brighten and soften, which suits dreamy or foggy moods.
  • Strong moves can introduce noise, dark corners or odd color casts.

A Step-by-Step Approach

  1. Set the basics first. Correct exposure, white balance and the white and black points before touching Dehaze.
  2. In the Effects panel, move Dehaze to the right in small steps. Values between roughly +10 and +30 are a reasonable first guess for global use.
  3. Watch the histogram and the shadows. If they clip, pull back or lift the Shadows slider.
  4. Use a Linear or Radial gradient mask on the distant hills or sky, and apply a higher Dehaze value only there.
  5. Check saturation. If colors feel heavy, reduce Vibrance or Saturation slightly.
  6. Zoom in to 100 percent and look for noise in dark areas, then apply noise reduction if needed.

Keep the Atmosphere Where It Helps

Haze gives a landscape depth, because distant layers look paler than near ones. Removing all of it can flatten the scene and make the picture look overprocessed. Try treating the foreground more than the background, so the sense of distance stays intact.

  • Apply less Dehaze to far ridgelines than to the mid-ground.
  • Leave some mist in valleys if it is the point of the image.
  • Compare with the original often to judge whether the edit helps.

Common Mistakes

The biggest error is pushing Dehaze too far, which leaves crunchy skies and harsh edges. Another is applying it globally when only one part of the frame needs it. Work in small amounts and favor masks over blanket changes.

FAQ

Can Dehaze fix a shot taken in thick fog?

It can improve contrast, but it cannot recover detail that was never recorded. Thick fog often looks better when you keep some of it.

Does Dehaze work on raw and JPEG files?

Yes, though raw files give more room before artifacts or banding appear in the sky.

The Short Version

Fix exposure and white balance, apply modest Dehaze, and use masks for the areas that need more. Keep enough atmosphere to preserve depth. Values here are general guidance, so adjust by eye for each photo.
