AVCaptureDevice: Flash or torch?

Question

Looking at AVCaptureDevice, there are properties for both torch and flash settings. They both seem to have the same methods. I know that "torch" is the British pyromaniacs' word for flashlight, but do these really do the exact same thing with two different names?

Answer 1

The difference is explained here. Basically, torch is used to continually illuminate video, whereas flash is used for image capture to brighten up the image. Hope that helps!
