Not for photo editing its for publications purposes

The purpose of this tool is to do math for artists and other creatives. We use this for calculating proportions for a piece for publication. It is not for regular folks to use to edit photos. DO NOT BUY THIS FOR THAT PURPOSE. That is not what it does. However it does do what it is meant to do. For me this is a good buy, because now I dont have to beat numbers out of my brain to come up with a size for my illustrations.
