Hi guys..i got a few questions i wish to ask..hope can seek can help here ^^
i am using D5100 and i have tried out the A and S mode..from what i have read, i understand that for the A mode, we got control of the aperture and the system will control the shutter speed accordingly, and opposite for the S mode.
But i realised that when i changed the aperture in the A mode, the shutter speed will change accordingly..so no matters what aperture i change to, the exposure of the photo will look the same..? (same case for P mode)
I am wondering if the resulted exposure is going to be the same, then why do we need to manual change the aperture or shutter speed in the first place?
Is it because if we use a slower/faster shutter speed, the image will be blurred/freezed while the exposure remains the same(S mode)?
