If you’re doing an image search for Paris Hilton and don’t want any of the French city, a special URL parameter in Google’s Image search will do the trick. Add

slick demo of its Photology software for organizing and searching through your digital photos. The downloadable software, which costs $29, only works on Windows, but the demo is set up to show how the software works using about 9,000 photos from Flickr. You can auto-magically sort through photos, searching by color, date, time of day, photo orientation, photo quality, location (inside or outside), or even for specific common motifs (such as faces, sky, snow, water, plants). I don’t know if the demo is canned, but if it is not, the technology is quite impressive. I played around with it and only got a few false positives. The screen shot below shows a search for red photos in focus.
