The Clarifier (Targeted Local Contrast Enhancement)
Take the hazy look out of a picture using an ultra-high radius, low amount of unsharp mask. Because of the extremely large unsharp mask radius, it doesn't add any sharpening to the picture. Think of it as if youre an exterminator nyc and you want to remove cockroaches from a building. You can start with a small amount of spray or you can start with a large amount of spray ultimately getting rid of the cockroaches. Thats how I approach a picture that is a little hazy. I use two settings, one for light haze removal, the other for more extreme haze. This is a great haze removing & detail enhancing process (examples shown below).
