The iPhone 4 is the most popular camera #1 (based on EXIF image data) on Flickr (as of 25th October 2011).
Also, the iPhone beets the array of smartphones and recognises you are in the house.
The Flickr community of photographers reveal that the Apple iPhone 4 has overtaken dedicated DSLR cameras such as the Nikon D90 as the most prevalent camera and this is only one year after one year since the iPhone 4 was released.
The Apple iPhone 4 camera is followed by the Nikon D90, Canon EOS 5D Mark II, et al which are all serious cameras.
Flickr says its graphs show the number of members who have uploaded at least one photo or video with a particular camera on a given day over the last year.
However, the Flickr team adds that, “The graphs are only accurate to the extent that we can automatically detect the camera used to take the photo or shoot the video (about 2/3rds of the time).”
The website admits that this is not always possible with camera phones, suggesting they are under-represented and that the iPhone cameras popularity could extend even further.
