I was working on some client files over the weekend when the ‘accident' above occurred. I was in photoshop CS5 and going to add a layer mask to the image when I accidentally clicked on the add adjustment layer icon, then the Posterize… feature, et voila!, the image above appeared. I was quite taken by the result have never posterized anything before.[ad name=”post”]
According to Wikipedia, posterization, “entails conversion of a continuous graduation of tone to several regions of fewer tones” and the term derives from the process used to make posters from photos.
Usually one wants to avoid posterization which can show as banding of colour in an image, say discrete bands of blue in a blue sky. But there are other times when it's worth cranking it up to eleven just to see what happens.
