Let's face it, hummingbird photography is high speed photography similar to capturing a bullet plowing through a watermelon. Since shutter speeds of a typical DSLRs are normally very limited, freezing this kind of action requires that the motion be stopped with flash. I know it is natural to think of high speed shutters when thinking about high speed subjects, but even with the most expensive DSLRs you are normally limited to 1/8000th of a second, and that just isn't fast enough to freeze or even acceptably limit hummingbird motion.

The wings of a Ruby Throated hummingbird beat at 50-60 times per second and have a wing span of 3-4 inches. This means the wing tips travel 6-8 inches from front to back, more or less. This also means that the wings travel between 300 and 500 inches per second. So a shutter speed of 1/1000 second will capture about 1/2 inch of movement which equates to a total blur of the wings. Of course the 1/2 inch distance isn't always true since the wings don't move at a constant speed. Instead, they move through one beat stop (or slowdown greatly) then move in the opposite direction . So catching detail in the wings means you would need a faster shutter speed than even very expensive DSLRs can provide.

Since shutter speed isn't enough to freeze or limit the action of hummingbirds, we use flash to do the job. Below is the flash duration of a Canon 580 EXII at selected power levels:

  • 1/1 power = 1/1000 second
  • 1/2 power = 1/2000
  • 1/4 power = 1/4000
  • 1/8 power = 1/9000
  • 1/16 power = 1/15000
  • 1/32 power = 1/21000
  • 1/64 power = 1/30000
  • 1/128 power = 1/35000

What this means is that the flash is only lit for the indicated amount of time, depending on the setting. If you adjust your camera settings so that no ambient light affects the shot, then apply flash at a reduced setting, you can freeze or limit motion blur.

Now, all of this may seem complicated, but it is really very easy; simply stated, instead of adjusting shutter speed to freeze motion, we use flash adjustments to freeze motion. That's easy.

The amount of motion (or wing blur) you allow will be a matter of your own taste. Some people like to see the wings of a hummingbird frozen, while others like some level of wing blur to imply motion and look natural. The difference is up to you. Experimentation will best help you undersand which you prefer. But, regardless of your taste, you can easily adjust your flash(s) to yield the results you find most appealing.
