What is the most important, assuming that you do not have lens fast enough to shoot without using a high ISO option without flash at an event, wedding or maybe even for night portraits.
A. Noiseless Image, use low ISO and just fire away with flash.
- Light up the subject and and get dark background and ambient lightings.
- No noise but got harsh flash directed at the subject, shadows at the background very dark.
B. Abit Noisy Image, increase abit ISO, fire away with flash then do Noise Reduction.
- Light up the subject and get some ambient lightings. The background becomes brighter, but the shadows caused by the flash still quite visible.
- Noise Reduction to remove noise. But still got very little bit.
C. Quite Noisy Image, increase more ISO, fire away with flash to fill in then do Noise Reduction.
- Subject, background and ambient lightings becomes very visible, background shadows barely visible, assuming not too much important details were lost.
- Noise Reduction to remove noise. But not enough to make the image as clean as option B.
