Contour Fashion

I use Photoshop 7. Open image. Next go to Image>Adjust>Auto Levels. Do this to all images that you open – from a camera, from the scanner or from the web.
Now go to Image>Adjust>Posterize.
Chose the levels (basically the number of values) you want – experiment. Lower numbers mean less areas of value and will be higher contrast whereas high numbers will have less contrast.
Final Posterized image.
