Color reduction/conversions, Mac Os

A recent forum post brought up the question that rises periodically on how to reduce colors in photographs, scans, etc. so as to be able to in turn use the image in a low resolution medium such as knit. There are very many ways to achieve this. The post had specifically asked for low cost or free alternatives using Mac software, so I began playing, and compiled the following document detailing some of my process, addressing large scale, non repetitive images in Color reductions for knitting.The document samples were simple, straightforward conversions, with no further “tweaking”.
