Want to take better pictures? Nikon School presents the Nikon Digital Learning Center, a great Flickr group that delivers loads of interesting and helpful tips and tricks to turn you into a better photographer. Experts and avid amateurs alike opine about portrait, action, travel, and close-up photography, with a bit of a bent towards Nikon technology.

I’ve only been on the group for a day now, but I’ve already learned some stuff about night shooting and heard some interesting views on how shooting RAW may affect battery life.

Visit the Flickr group today – and if you don’t have a Flickr account yet, you can join up.

As most people who use digital cameras knows, the camera records a bunch of information inside every image. This information is known as EXIF, and one of the key pieces of data it records is the camera make and manufacturer. A website known as BigHugeLabs keeps a list they update weekly which tracks the most popular cameras used on Flickr.

When people upload pictures to Flickr, they usually leave their EXIF data intact (ie. they haven’t performed any EXIF damaging editing on the file). Flickr will accumulate all the numbers and do a report every so often – which BigHugeLabs references. You can get the details on the top 10 cameras being used at any given time there.
