One of the announcements from yesterday's Nintendo Direct broadcast was a 3D photo contest campaign for 3DS owners. Nintendo shared details today via a campaign site (which is hosted on what appears to be a new Nintendo domain: "nintendonetwork.net").
Starting January 18, Nintendo will host a series of 3D photography contests. Participants will submit their 3DS photos to the campaign site. Celebrity judges will select the top submissions, whose creators will receive prizes.
Photos can be submitted exclusively via the 3DS. The actual campaign site can be viewed on your PC or on the 3DS. If you view on the 3DS, you can view the submissions in 3D.
Further details will be announced later.
