I have Powershot D30 which I'm intending to use from a drone (quadcopter) to measure the condition (i.e. shape) of whales and dolphins, to see how that relates to breeding success. Obviously the images need to be sharp, taking at reasonably high shutter speeds.
I see a way to force a particular shutter speed, but can you set a minimum shutter speed in P mode, or even better, activate a shutter priority mode?
Any advice gratefully received.
