The Narrative Clip 2 is an oddity in the photographic world: an almost entirely passive camera. Under most circumstances, you don't frame your shots, you don't choose when they're shot, and you don't even hit the shutter button.
Essentially a tiny little box you can clip to your lapel (or anything else), it's designed to snap a photo twice a minute for as long as it has power. (If you want to take a more active role, you can tap the device twice to snap a frame on the fly.) Privacy advocates might take issue with the concept, but the intent is actually pretty innocent.
The reasons you might want a camera like this are pretty simple. For one thing, the presence of cameras tends to make people pose or freeze up, meaning you don't get naturalistic shots. The Narrative Clip is almost totally incognito, letting you get otherwise impossible shots.
Second, the Narrative Clip 2 allows you to document your entire day (the battery lasts 30 hours), creating a snapshot record of where you've been, who you've seen, and more. Chances are, you'll get at least one or two interesting shots every day.
The Narrative Clip 2 features a higher-resolution camera (8 megapixels) and a wider-angle lens than the original Narrative Clip. It will retail for $199 when it launches later this year.
