I downloaded Picasa from google, it is free and is an easy to use program. it has facial recognition and creates pencil drawings. i scanned old dark photos and it lightened them up enough to even see people on the sofa in the back ground of the photo. it also does collages too!
picasa.google.com a setting came up and asked me what pictures to open with picasa and i set them all to load with picasa, after you save your picture to a file, open up that picture and click on it. at the bottom of the screen it will say to edit with picasa. your picture will open in a new window ready to be edited. be sure to go to file and save as a new picture. very easy using the tabs at the top of the page, hope you will give this program a try, fun to use and easy too. free and safe is the best part!
