These 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.

The graphs are "normalized", which is a fancy way of saying that they automatically correct for the fact that more people join Flickr each day: the graph moving up or down indicates a change in the camera's popularity relative to all other cameras used by Flickr members.

The graphs are only accurate to the extent that we can automatically detect the camera used to take the photo (about 2/3rds of the time). That is not usually possible with cameraphone photos and cameraphones are therefore under-represented.
