Photoscape strikes us from the very beginning with an uncommon interface design from which you can choose what you want to do: view pictures, optimize those that didn't come out so well, print several photos on a single page collage-style or perhaps add any of the dozens of filters and special effects included in the program. Other extra tools featured in Photoscape are a file renamer, a color picker, a screen capture tool and even a RAW converter.

We really have nothing negative to say about Photoscape. Just download it, test it, love it and keep it forever. It's free!
