Nintendo 3DS Camera App: No Stamps, But Drawing Tools and AR Features Exist

The Nintendo 3DS Camera / Photos app (not "Photo Channel"—that's the Wii) does not have a stamp/sticker library. The Wii Photo Channel included Mario, cat, dog, and other stamps; the 3DS does not.

3DS Camera App Features

• View: 3D (MPO) and 2D (JPG) photos from cameras or SD card.
• Edit: Crop, rotate, color filters (B&W, sepia, negative, dream), draw with pen/brush tools (stamp-like brushes, not a sticker library).
• AR Cards: Photograph AR cards for mini-games via the AR Games app.
• Share: StreetPass (swap photos with nearby 3DS), Facebook/Twitter (deprecated), SD card export.

On 3DS, "stamps" = drawing tool brushes, not a pre-made sticker collection.
