I'm an amateur photographer. I love to take pictures, but iphoto only provides limited editing and photoshop is pretty pricey. So, when I learned about www.picnik.com, I had to try it out.
Here is a pretty basic photo and I used just a few of their different effects to give you a taste:
Original - Canon point and shoot:
Auto fix - added a little more clarity and vibrancy:
Black & White w/ spot color - I am so excited that I can do this to my pictures now:
1960s - love, love, love the rounded edges:
HDR-ish - brings out every little detail
Orton-ish - no idea what that means, but it could look really cool on a different photo
Focal Zoom - feel like I am in a vortex on this one
Pencil Sketch - also could be really cool with certain photos
That is just a taste of the many different effects they offer. Plus, within each effect you can control different levels, like how much blur, brightness, etc.
Really, it is a lot of fun to play on the site, and it is free! Enjoy!
