# Freezing bee's wings motion

Jan 15, 2015 03:10 |  #16

I have search for the method to shoot flying insect, this was I found on internet, but I never try.

I think freeze the wings very hard in ambient light.

The most effective technique of reliably freezing fast insect motion is to use electronic flash, which has a shorter duration than all but the fastest shutter. Engineer Harold Edgerton set the standard decades ago.

Just to highlight the problem in calculating the shutterspeed needed to freeze wing motion. Even if you knew the highest wing beat, the actual velocity of the wings would vary. The speed at the wing tips would be much greater than at the wing base. In other words, for a given beats per minute figure, the velocity of the wing tip would be greater as the wing got longer. There's another variable to, and that is wing flex. This could both slow down the velocity, and increase it with a whip like effect. I'm not trying to confuse things. I've never gone into it in depth, but the shutter speed needed seems to vary. I'm aware of the point Brian made, where the wing beat will change direction, and there is a point where for a fraction, motion stops. However, in practice even mid-stroke the shutter speed needed to freeze the motion, appears to vary a lot. I suspect what causes this is that insects speed up and slow down their wing speed, as they are maneuvering. From what I know, to reliably freeze wing motion you need a very high shutter speed, possibly as high as 1/10,000 or faster.
