I think that Picnik is the best photo editing application avaliable for free use. Unless you own photoshop or photoelements then there is no program out there that is as easy to use and has as many functions.
This is the photo that I have played around with and found it so easy to use. I could adjust the color, select Black and White for some sections and color for others. I was performing tasks that take alot of effor twith advanced photo programs with ease. It is and AWSOME tool.
This site is great for students to use to create their own artwork and photo adjustments.
Hope everyone else loves this site as much as I do!!
