I wanted to make several photos for a time lapse but I wanted to decide the exact moment the photo was taking. The phone is in a tripod, so touching it was cumbersome. I could have bought a remote BT shutter, but it was a little overkill for just one timelapse.
Automagic to the rescue: I come up with the idea that the http request trigger from Automagic could act as a remote trigger, just pointing the browser to the web address of the phone.
As a bonus once the photo is made it writes back a thumbnail to the browser, so that you can see the progress (try to do that with a remote shutter

The delay is because sometimes the flow fails and I suspect that it is because the camera needs some time to process and write the file.
Obviously, the phone and the PC should be in the same network.
