Color banding (or posterization) is a common type of image artifact especially noticeable in low-quality photos featuring gradients or large areas of solid color. I see this all the time in wallpapers and landscapes.

Instead of smoothly blending together, colors jump abruptly from one shade to the next, forming distinct bands of color. The latest Pixelmator Pro release takes all the work out of debanding with its “Deband” button. Push the button. The bands go away. It’s that simple. Behind the scenes it is using machine learning to pull this off.

I purchased Pixelmator Pro when it first launched and continue to find value in the purchase as they continue to solve annoying photo problems for me.
