Basically, it's like an online version of Apple iPhoto's Enhance tool or Google Picasa's I'm Feeling Lucky button but essentially better than both of those. All you do is upload an image from your system or give it a URL to get it from and it automatically restores true original colours, corrects colour temperature and adjusts for poor lighting. There's nothing else to do and all you get is the option to download the improved image.
I tried it out with a couple of my images and the results are subtle but that's probably because I'd already tweaked them a bit. The next time I get a few fresh off the camera I'll see what this site can do for them. Anyway, if you're unhappy with the results you're getting while trying to tweak a problem pic with your image editor or just don't have the time to play with the likes of Photoshop or the GIMP, then this is definitely worth trying out.
