From time to time, the technology of digital cameras can introduce unwanted artifacts. One type of artifact that you can fix with Photoshop is an excessive amount of colour noise or colour blooming. You’ll most likely see this problem when shooting with a high ISO setting or with a low-end digital camera (cell phone cameras). The added colour artifacting doesn’t represent the true colour of an image. I call this phenomenon “The Colour Gremlins”.

In nature when doing landscape work that includes sky, especially early or late in the day, the contrast range encountered often exceeds that which film or imaging chips can handle. It's therefore necessary to find a way to reduce the contrast range to something that the camera can handle so that the highlights don't burn out and the shadow areas don't turn inky black.
