Some of you, who read my other blog, Antony’s Mobile Blog, may feel de-javu. Yes… this tip, Viewing Exif Information from JPEG Images, is actually an old posting from my other blog. I decided to write the same posting here because I just realized that Nokia N73 is the most popular camera phones on Flickr. If you don’t know what I am talking about, please visit Flickr’s Camera Finder page.
Some of you may ask, how does Flickr publish this statistics? How does Flickr know which camera model a photo is taken from? The answer to this question is Exif. Here is an explanation of Exif from Wikipedia:
Exchangeable image file format (official abbreviation Exif, not EXIF) is a specification for the image file format used by digital cameras. The specification uses the existing JPEG, TIFF Rev. 6.0, and RIFF WAVE file formats, with the addition of specific metadata tags. It is not supported in JPEG 2000 or PNG.
Basically, Exif is metadata embedded into images captured with digital cameras, including camera phones. Not only camera model, Exif stores many other parameters, such as focal length, exposure time, aperture value and many more.
We can also view Exif information from our PC. There are many photo management software, such as Google’s Picasa, and image viewer software, such as IrfanView (with additional plug-in), that are able to display Exif information. Windows Explorer is able to display Exif information too (just right click the file name and select Properties menu).
The following screenshot shows Exif information from a picture taken with Nokia N73. Just for your information, I use Picasa to display Exif information. You can display Exif information by right click the picture on Picasa and select Properties menu.
Compatible devices: S60 1st, 2nd, 3rd Edition, Nokia Nseries, Nokia Eseries.

You don’t need special software to see EXIF info on Windows. Just right-click on the image file in Windows Explorer, and choose Properties. Go to the Summary tab and bring up the Advanced view.. all your Exif info will be displayed

Apple iPhoto natively supports this feature.

@luca: Thanks for adding this. As I said on my posting, many photo management software already supports this feature. So, basically we can view it using any of them.
