    I REALLY suggest you try to read a book called "Understanding exposure" by Brian Peterson. You need to understand exposure to know how to handle different situations.

    Yes.

    But under low light condition, u might not be able to get the correct exposure. U will really appreciate higher iso setting in this case.

    1. Lower ISO setting (i.e. 800 to 400) then increase you exposure by +0.7 or +1 stop.
    -0.3 will be best

    Let's sum it up based on all the posts as well as my suggestions:

    1. use a flash
    2. use a fast lens
    3. use a camera with good noise handling
    4. use noise reduction during post processing
    5. use antishake body / lens
    6. use tripod or improvised support
    7. learn to stabilise your hands
    8. underexposure
    9. switch on more lights at the subject
    10. ask the subject don't move
    11. convert pictures to black & white
    12. learn to accept noise

    i think we are looking at 2 different things.

    I am thinking that he should reduce exposure to achieve higher shutter speed so that he can reduce ISO thus reducing noise.

    Your overexposure means masking away the noise, but this will loose image details.

    Depends on your camera body, really. Some respond better to underexposing, others to overexposing.

    - snapped from far.. accidentally blasted the ISO to 3200


    - at ISO1600


    - closer up a bit at ISO100 - which I find the color is much better than higher ISO setting.. what do you all think?

    From these "play-around" without using tripod, I came to appreciate low ISO = less noise, while higher ISO setting = absorb more light but make it look noise.. - correct me if I'm wrongly interpret.

    As a principle, I die-die try not to set at ISO3200 to avoid the "noise" but if lighting is so bad I do compromise at times

    At very high iso, the color will become less vibrant, not to mention softness which you have already experienced. It is normal across all cameras except that larger sensors will experience loss at a higher number.
    Foveon fares more badly at higher iso from loss of color than Bayer.
