Helicopters are even more difficult to photograph when attempting to achieve this effect. Since helicopter blades are much larger than propellers, they don't rotate at such a high RPM; therefore an even slower shutter speed must be used. I tend to set the camera between 1/60 and 1/125 of a second. Try to support your camera with a tripod or monopod and if that is not possible, use a flight-line fence, barricade or post to do the job.

Most importantly, if you feel the shot's worth getting, take many. Even if you feel as though you were steady as a rock, our natural progression of movement when depressing the shutter button is to dip the front of the camera. Even pros with many years of experience have to throw out images because of this phenomenon. And while we're on the topic…you are supporting the lens with your other hand, right? This will help fight against possible movement during exposure.

 

Most of all…Have Fun!

Go with friends and family, enjoy the atmosphere and don't be afraid to look around. There are many other things to be seen while everyone else has their eyes glued to the sky.
