The new Dehaze control in Lightroom CC and Adobe Camera Raw 9.1 can help you to dramatically improve an image by removing haze. The Dehaze technology is based on a physical model of how light is transmitted, and it tries to estimate light that is lost due to absorption and scattering through the atmosphere. For the best results, you’ll want to set the white balance for the image before using Dehaze. Then, in the Effects panel, move the slider to the right – to easily remove the haze from the original scene. Move the slider to the left to add a creative haze effect.You can choose to make very subtle to very significant adjustments – if you’re pushing the slider to the extreme, you might want to refine the image using the Basic panel (increasing the shadow detail or refining the Vibrance slider) in order to achieve the exact look that you’re after. Check out the video below to see Dehaze in action.
When moving the slider, there is very little change in the highlight area (on the right side of the Histogram), while the shadows and lower portion of the histogram is clearly being changed. If you are concerned that the darker values in the image are being clipped to pure black, Option (Mac) | Alt (Win) -drag the slider to see the black point clipping visualization. When you see black areas appear in the image, you know that you’re starting to clip to pure black and can back off. In addition, Dehaze can be added locally by applying ACR as a Smart Filter in Photoshop.
