Don’t get fooled by the word ‘PRO’ in the title of the post. Sigma Photo (Pro) Software is an exclusive software package for displaying and manipulating your Digital camera images on your computer.
Technically speaking, this is not a Freeware since only owners of Sigma cameras could download and use it, but then, we all own a Sigma camera! Don’t we? 
It has all the basic features of a photo editing tool like adjusting colors, hue, saturation etc and seems a worthy tool to do some quick optimization of your digital images. If you are not a ‘pro’ I suggest you to download and use it for some simple yet effective optimization of digital images.
