Nikon has done a great job of featuring the work of Flickr users in their Nikon Stunning campaign, and the Nikon Stunning Gallery tag on Flickr. Now they’ve taken it up another notch by introducing the Nikon Digital Learning Center group. It’s a great idea, marred only by a very unpleasant copyright license policy for pictures in the pool. That doesn’t seem to extend to the discussions, so you could still post pictures there in order to gain educational value from the group. That flaw aside, this Nikon seems to be pounding Canon into the ground as far as their use of Flickr. Oh, and their ability to produce an ISO 25,600 DSLR.
