    Default ISO help for macro shots

    Thanks to madmartian, james, and many other csers, i think im improving

    one more question, iso setting.
    i know for macro shots, thanks to csers, that aperture should be set to 16+- , shutter speed depending on lighting, but now iso. some say 100/200, some say 400/800. how?

    Personally,

    Most macro are done with a flash at a close distance. Rather than compensating the shot with a higher ISO, the flash should be sufficient. This comment is even more true for night macro.

    Not forgetting the fact that the higher noise level that comes with a higher ISO~

    Just my thoughts~
    Enjoy macro~

    Cheers~

    Depends.. Personally, i do not want my flash to overpower the ambient..In tricky lighting conditions, i still will set slightly higher ISO (400-1200) to compensate for greater dof without altering my aperture yet i can still capture my subject at a reasonably acceptable shutter speed.

    Though rule of thumb is always use the lowest ISO number possible to retain the highest quality image, but that may not applies to all , esp with the availability of high iso capable bodies like D700..

    Agree with the above if you have a high ISO capable body. However, under tricky lighting isn't it better to use a flash?

    Macros can be done from f2.8 to f22. It all depends on your requirement and what you need to do. Less DOF or more.

    The ISO is a balance, I do night macros handheld and would not be able to use low ISO, thus I compensate by using a medium ISO of about 400 with lowered flash settings.

    How come u all prefer f8 for macro?

    Cos i always go for the biggest aperture like f2 to blur the backgrd and focus on the primary object instead?

    The closer the distance fo the cam to the subject, the lesser DOF you will get. Even sometime for macro, DOF at f8 is still very thin

    You can use DOF calculator to check

    thanks all, lower iso for better quality, higher to compensate for lighting. got it. thanks everyone

    If you're shooting at f2.8, then you're not shooting at the maximum magnification. In which case, then the DOF at that distance is not critical. But if you're shooting at the minimum focusing distance, then you'll realise that even f8 may not be enough to get the insect fully into focus.
