If you plan on using this camera, make sure it's charged ahead of time! You can plug it into a computer with the USB cable, or for faster charging, it can be plugged into an iPod power adapter (full list of compatible wall adapters). Note that it will likely be faster to use a wall adapter than to charge through your computer.


Here are some useful links to start using the camera. You can take a picture using the button on the top of the camera. Once you've taken a picture, you can view it by swiping the touch interface from left to right. You can then sharpen a region by tapping it once. If you want to zoom in, double tap, then move around, and single tap to focus on the zoomed in region; to zoom out again, double tap once more.


Here are tips on how to shoot pictures that will give dramatic effects when selectively blurring regions in the pictures. Generally, you should try to get really close to your near-depth object when shooting; if there's a bit of blur, that's good!
