This works on any photos or wallpaper on your computer. Yes this is very basic. You can ajust the exposure, contrast, shadow, highlight, saturation, sharpness and color. You can also rotate pictures.

To be honest, this freebie is not meant for everyone but only for owners of Sigma cameras.

Nevertheless, you could download and use it if you wish to. And perhaps, buy a Sigma camera later on.

I don't know much about photo editing tools but I believe this has all the basic features that allow you to do some quick optimization of your digital images.

A small update:

Sigma Photo Pro isn't a commercial software...hence, I don't think it's right of me to call it a freebie.

It is listed as a freeware at Softpedia; here are the links:
