Dehaze

Dehaze rebuilds the contrast and color that atmospheric haze removed from a photo. Haze scatters light between the camera and the subject, which leaves distant areas pale and flat. The slider estimates how much haze sits in each part of the image and restores punch where it finds the most. Positive values cut haze; negative values add it for a misty look.

The contrast slider pushes all tones apart evenly across the whole photo. Dehaze targets the areas haze flattened, usually distant subjects and skies, and leaves clear areas mostly alone. Dehaze also boosts saturation and darkens the image as it works, so the two sliders produce different looks even at similar strengths. Many edits combine a small amount of each.

Clarity raises midtone contrast across the frame, which makes textures and edges pop. Dehaze models atmospheric haze and removes it, which changes color and brightness along with contrast. Clarity suits texture-heavy subjects like rock, fabric, and skin detail. Dehaze suits hazy landscapes, city views, and night skies. The two often work together: dehaze clears the veil, then clarity sharpens the texture underneath.

Negative dehaze adds haze instead of removing it. It lowers contrast and saturation in a way that mimics mist or fog, which gives photos a soft, dreamy mood. Photographers use it on portraits, forest scenes, and backlit images where a gentle glow helps the subject. Small negative values can also soften harsh digital sharpness in some images.

Removing haze darkens the image because haze added brightness to begin with. The slider also shifts colors cooler, since haze carries a warm or neutral cast that gets subtracted. Both side effects grow with the strength of the move. Raising exposure slightly and warming white balance after a strong dehaze adjustment usually brings the photo back to a natural look.

Yes, strong dehaze makes noise more visible, especially in smooth skies and shadow areas. The slider amplifies faint differences between pixels, and noise counts as a faint difference. RAW files tolerate more dehaze than JPEG files because they store more data. Keeping values moderate, applying noise reduction afterward, or limiting dehaze to a masked area all help.

No. Dehaze recovers detail the atmosphere dimmed but did not destroy. Light haze leaves detail behind the veil, so the slider can restore it. Thick fog blocks light completely, and no slider can rebuild detail that never reached the sensor. In heavy fog, dehaze mostly raises contrast and noise without revealing much. Embracing the fog as a subject often works better.

Global dehaze works when haze covers the full frame, such as a distant landscape shot through humid air. When only the sky or the background looks washed out, a local adjustment works better. Masking tools in Lightroom and similar editors can restrict dehaze to a gradient or a selected area, which keeps the foreground contrast natural.

Adobe Lightroom and Camera Raw popularized the dehaze slider, and Capture One, Luminar, darktable, and many mobile editors now include a version of it. Names vary; some apps call it haze removal or atmosphere. The controls behave similarly: one slider that removes haze when raised and adds it when lowered.

Night skies suffer from light pollution glow, thin clouds, and airborne moisture that wash out stars. Raising dehaze darkens that glow and boosts contrast between stars and sky, which makes the Milky Way and faint stars easier to see. Astrophotographers often pair dehaze with clarity and selective noise reduction, since the same move that reveals stars also amplifies sky noise.
