photo enhancment

:confused hi guys and girls. need a lot of help.what is the name of the program that allows you to view and sharpen up a digital photo that you have taken.

 

PhotoFiltre isn't a viewer exactly, but is a complete photo editor.

For viewing and organizing lots of photos and batch editing, XnView is a good choice.
