Welcome to Tutorial Tuesday, by COAP Online

Your shutter speed is one of the most effective ways to change the feel of an aviation photo. It does more than control camerashake and sharpness… You could even say it also has the power over action and realism.

Why jets and props need different shutter speeds

Jets and props/rotors behave very differently.

With jets, there is no visible propeller or rotor blur to communicate motion. The sense of speed comes from the pose, the  phase of flight, background, heat haze, vapour, and the way the aircraft sits in the frame. A faster shutter speed often makes sense because it keeps the aircraft crisp and protects detail, especially during fast passes at airshows.

When a jet is caught against a background (say low-level terrain, or simply on take-off) then choosing a slower shutter speed and combining it with a good panning technique is the absolute key to conveying motion.

With prop aircraft and helicopters, the spinning prop or trashing rotor blades are major parts of what makes the image feel authentic. If your shutter speed is too fast, the prop will freeze into an odd shape that looks unnatural and sucks the life out of the aircraft/helicopter into a still-motion ‘model’. The fuselage may be sharp, but it can feel like the it’s falling out of the sky. It’s that unnatural.

A practical way to choose shutter speed

Instead of hunting for one “correct” number, decide what you want the photo to say:

• Frozen action look: higher shutter speed, maximum crispness
• Natural motion look: slower shutter speed, some prop or rotor blur, airframe still sharp
• Speed and energy: panning with a slower shutter to blur the background while keeping the aircraft readable

The biggest skill that makes slower shutter speeds easier

If props and helicopters feel hard to get right, it’s rarely because the shutter speed is “wrong”. It’s usually tracking technique. Smooth panning, good stance, and keeping the AF point where it needs to be matters more than obsessing over exact settings.

A simple exercise is to shoot a prop aircraft at one shutter speed for a whole pass, then drop the shutter speed one step for the next pass. Compare the results and look specifically at the prop blur and cockpit sharpness. If you lower the speed far enough to get to the point where you’ve got loads of blur in the props/rotors but the fuselage is suffering from camera shake, then you’ve gone too far. You’ll quickly find a range that suits your lens, it’s image-stabilisation capabilities, your steadiness, and the subject’s speed.
