Apple headphones as remote shutter release with Slow Shutter Cam app

It pays to read the instructions! Now that I have a tripod, I'm going to test out the Slow Shutter Cam app () on the next clear sky I come across. Since my PowerShot has a max exposure of 15 sec, I was thrilled to see this little app has a "bulb" exposure feature (unlimited time). The only problem was that I would have to tap the screen to end the exposure.

Well, according to the instructions, you can use Apple's earbud headphones as a remote shutter release by pressing the "+" button when the app is open.

Update: The volume (+) button works for the regular iPhone camera as well, in case you didn't already know that.
