Flickr is doing a little Web 2.0 style data mining with their Camera Finder service, a Yahoo! Shopping sponsored look at what cameras the users of Flickr are shooting with. Featuring all cameras, point and shoot cameras, and cameraphones, the graphs “show the number of Flickr members who have uploaded at least one photo with a particular camera on a given day over the last year”. Though the data is only available for cameras that Flickr can autodetect (about 2/3rds of them), it’s definitely an interesting new way of rating products. The Canon EOS Digital Rebel XT and PowerShot SD400 (my camera of choice) lead their respective categories, while Sony Ericsson dominates the cameraphone market. If you’re in the market for a new camera, this is definitely a service to keep an eye on.
