p.1 #6 · p.1 #6 · Question how to estimate minimum shutter speed to handhold macro | |
There are two components of motion in photography: that of the cameras/lens and that of the subject (if the latter is not e.g. a building). (Dalentect mentioned this). The former can be eliminated by a tripod, where practical (wind can still move a large, long lens with a large hood). Unless the latter is an inanimate object it is likely to be the major contributor (locomotion of an insect and/or its substrate moved by a breeze, or the stem of a flower moved by even the least air movement.
So, with ambient light, you need a shutter speed to freeze any subject movement and (hand-held) to overcome any unsteady hands. Regarding the latter, I have sometimes reduced shutter speed to let the IS sort that out.
Not quite addressing the immediate issue, but maybe of interest: some experimentation with higher than minimal ISO showed that (manual operation, manual flash) I could use at least two shutter speeds higher than the specification for the camera stated for flash synchronisation without losing part of the frame. Check your gear for this before using it on a vital shoot!
