I recently treated myself to a Nikon D3100 and it's time to turn the Mode dial from Auto to something more constructive!
Could someone explain to me the difference between P and A, please.
I understand that, in S mode I get to choose the shutter speed, the camera adjusts the Aperture to suit.
In A mode, I get to choose the Aperture and the camera adjusts the shutter to suit. In P mode, initially, the camera gets to choose both but I can adjust the Aperture and again the camera will adjust the shutter to suit.
So how does P differ from A?
