Reducing Haze
You can use the Dehaze tool to restore contrast, detail, and lost color to images. This tool is especially useful for images that have been captured through a haze. A haze can occur when dust, smoke, or other particles obscure the clarity of the image, particularly the sky.
To Dehaze an Image:
- In Edit mode, in the Exposure/Lighting group, select Dehaze.
- Drag the Amount slider to adjust the strength of the correction.
- Do one of the following:
- Click Done to accept your changes and close the panel.
- Click Cancel to discard your changes and close the panel.
You can also access the Dehaze tool from the Filter drop-down menu or Filter toolbar.
You can right-click a slider to reset to the default value.
You can use the Edit Brush 
to paint this effect onto specific areas of your image.
You can use the Gradient tool 
to transition this effect across specific areas of your image.
You can use the Radial Gradient tool 
to apply effects around, or directly to, a center point.
