to take a pic with this app you have to open it on your phone, open it on your pebble, connect your pebble by tapping on the phone app, and then you can take a picture with a pebble button. images are good quality, comparable to native camera as far as I can tell. Live preview on pebble time is monochrome, buggy, slow and low rez, basically useless.
this is the best app I could find for this pebble function. I wish I could perform this pebble function using only the pebble itself rather than having to open an app on my phone but this is almost as good.
