Pixlr.com

After writing that last post, I wanted to see if there were any good online photo-editing programs that are free to use. I found pixlr.com, and it's pretty good.

It even has a 'solarization' feature, although it pretty much sucks. It just inverts the image and then darkens it a little. The Picture Manager way produces much better results.

However, I did spend some time fiddling with it, and it's quite easy and fun.
Here's some of my favorite features-

In the 'Adjustment' menu:

Cross process
(I don't know what it does, but it's cool.)
Color lookup
(Basically a selection of kickass premade gradients, but it also allows you to make your own.)
Curves...
(Allows you to make your own solarization effect, and generally mess with the picture's contrast. Just click on the diagonal line and drag it up or down, then click on it in a different place and drag it again.)


In the 'Filter' menu:

Polar coordinates...
(It takes a long time- it may look like your computer has frozen, but the effect is almost worth it.)
Water swirl...
(pretty much what it says. Pretty awesome.)
Heat map...
(turns things from blue/green to orange/red, depending on how high you set it.)
Kaleidoscope...
(hands-down the coolest effect. I could amuse myself with this for hours.)

Have fun!
