I'm not a photographer: I don't even own a camera. (Well, my laptop has a built-in webcam. I'd prefer not to go out photographing with it.) It has happened, however, when I've felt that some articles needed illustrations and no one better suited seemed likely to do anything about it, that I've borrowed a camera and taken some photos. They aren't edited in any way. You're very welcome to do that, if you want to use any of them somewhere.
The best thing I do at Commons is probably to import more photographically talented friends' and acquaintances' pictures from Flickr, sometimes after convincing them to relicense the pictures under a more Wikipedia-friendly Creative Commons license. Their photos tend to be technically better and/or more useful.
I write about Wikipedia (in Swedish) on Wikipediabloggen.
