How does flickr know my pictures are taken with my n95?

I have recently put some pictures on flickr, and i looked at them and at the side it says that they were taken with a Nokia N95, which they were, but how did it know?

Flickr's just clever like that!
Reply:My camera even shows what hour, minute and second that the picture was taken.
Reply:Flickr interprets the Exif data embedded in each photo with it present and uses it to display the camera make and model, date and time it was taken, camera settings, and even where if it contains geographical information (with use of a GPS unit).

Reply:The data is embedded into the files.
Reply:Some high end cameras even go so far as to embed the serial number of the camera into the image data, this helps if you ever need to prove the image is yours.
Reply:All digital image files store information on the camera, including the make, model and sometimes things like f/stop, shutter speed, flash on/off, ISO, etc.





Mine even stores my copyright notice in an Image Comment.
Reply:All raw digital image files contain encoded information about the picture. When you upload your images to Flickr it stores that information too, including when it was taken, what aperture you used, what ISO etc. You can view some of the information yourself in Photoshop under File Info.
