How to read this page
Dehaze reduces atmospheric veil
Dehaze comparison focuses on haze, fog, mist, and atmospheric veil. Positive dehaze can restore distant contrast and color separation, while negative dehaze can add a soft veil. Use the comparison to check whether the scene gained depth or became harsh.
Scope
Dehaze can resemble contrast or clarity in some regions, but this page focuses on haze-like low-contrast, low-saturation bright areas.
Dehaze comparison guide
What Dehaze Comparison Shows
Compare haze removal
Check whether distant detail and atmospheric depth improve when you remove haze from a photo.
Watch sky and highlight risk
Dehaze can quickly push skies, clouds, and reflections too hard.
Dehaze vs clarity
Dehaze targets atmospheric veil; clarity targets midtone local contrast.
Dehaze terms and haze checks
How to Read an Image Dehaze Comparison
Image dehaze comparison is for haze, fog, mist, and atmospheric veil. It should not become a generic contrast or clarity page, even though dehaze can affect contrast and color.
A useful review checks distant detail, washed-out bright low-saturation areas, local contrast, color boost, and sky clipping risk. The best result keeps atmospheric depth without making skies or highlights harsh.
Haze mask
A haze mask is a soft estimate of bright, low-contrast, low-saturation regions.
- Role in the image
- It focuses dehaze review on areas likely affected by atmospheric veil.
- Concept or calculation
- Luma, chroma, local contrast, and image position can contribute to a soft mask.
- Watch for
- Do not treat the mask as semantic sky detection.
Atmospheric veil
Atmospheric veil is a washed-out layer caused by haze, fog, mist, or distance.
- Role in the image
- It is the main visual problem dehaze comparison should address.
- Concept or calculation
- Veil often appears as high luma, low saturation, and low local contrast.
- Watch for
- Some scenes intentionally have soft haze and should not be forced into maximum contrast.
Local contrast
Local contrast is nearby tonal separation improved by dehaze.
- Role in the image
- It can make distant objects and landscape layers feel clearer.
- Concept or calculation
- A local luma difference from a blurred neighborhood can estimate this change.
- Watch for
- Too much local contrast can make haze removal look crunchy.
Sky clipping risk
Sky clipping risk warns when sky-like bright areas approach display limits.
- Role in the image
- It protects skies, clouds, and reflections during dehaze review.
- Concept or calculation
- Bright, low-saturation upper-image regions can be checked for near-white clipping.
- Watch for
- This is a heuristic and should be confirmed visually.
Negative dehaze
Negative dehaze adds haze-like softness.
- Role in the image
- It can be useful for a softer atmospheric look.
- Concept or calculation
- The adjustment can reduce local contrast and color separation in haze-like regions.
- Watch for
- Too much negative dehaze can make the image flat or washed out.
Dehaze vs contrast
Use contrast for broad tonal separation. Use dehaze for haze-like low-contrast atmospheric regions.
Dehaze vs clarity
Use clarity for midtone local texture. Use dehaze for washed-out distant contrast and atmospheric veil.
FAQ
About this page
Is dehaze the same as contrast?
No. Contrast changes tonal separation broadly. Dehaze targets haze-like low-contrast atmospheric regions.
Is dehaze the same as clarity?
No. Clarity changes midtone local contrast. Dehaze focuses on atmospheric veil and distant contrast.
Why does dehaze make colors stronger?
Removing haze often increases local contrast and chroma, so colors can appear more intense.
