I keep reading about 3rd parties taking advantage of the low light mode on the iPhone 5, and from screenshots of Camera+ it looked like you could select low light mode. With the built in camera app, is this automatic? I assume it is, and that you can't turn it on and off? With it really bumping the ISO it would be nice to select it, like the HDR, and have the camera save both pictures even. Anyone test this themselves with the built in vs 3rd party apps? I'm wondering if I should install Camera+ for this, I have always just used the built in camera app.
