When you shoot in lightroom, the camera automatically creates a histogram to help you understand how your photo looks. This histogram is a representation of how the photo looks before it is processed. To dehaze a photo in lightroom, you need to use the Dehaze tool. This tool can be found under the Image>Dehaze menu item. To use the Dehaze tool, first select your photo and then click on the Dehaze button. The Dehaze tool will start working on your photo and will change its color according to how much it has been changed. You can also use the slider to control how much dehazing should be done to your photo.
