    I use ACR mostly.

    I've noticed dehaze has more or less the same effect as boosting the contrast slider. Should you use both or just one or the other? What's the difference? How do each affect the photo?

    Thanks in advance for help.

    Dehaze is more similar to moving up the black point in Levels.
     
  4. The primary purpose of the Dehaze tool is to eliminate or minimize haze in the atmosphere, though it can be used for other purposes especially if used in small amounts. Before that tool was added to software applications, we minimized haze manually by increasing the contrast and/or darkening that area of the scene. (I always did it using the tone curve.) We also added warmth to counteract the cool tones inherent in distant haze. To replicate that manual process in a more automated manner, the Dehaze slider, unlike the Contrast slider, also adds warmth. If you slide it all the way to the right purely for demonstration purposes, you'll easily see the added warmth.
