How to use shutter angle

What is shutter angle?

In a nutshell, shutter angle is a way of describing shutter speed relative to your frame rate. The term originated in the era of film cameras, when rotating shutters were measured in degrees. While today’s digital cameras don’t physically use the same rotating shutter system, the term has remained and is still used to describe the relationship between exposure time, frame rate and motion blur in video.

How is it different from shutter speed?

Put simply, shutter speed is a fixed value that determines how long each frame is exposed, while shutter angle is linked to frame rate, helping you maintain consistent motion blur when frame rates change.

When should I use it?

You may find it helpful to keep your camera set to a shutter angle whenever you are filming. That way, when you switch from 25fps to 50fps or 100fps, you don’t need to think about changing shutter speed, which helps maintain consistent, natural-looking motion.

What shutter angle should I use?

A common rule of thumb in filmmaking is to use a 180° shutter angle, which gives a shutter speed roughly double your frame rate, so if you are recording at 25fps, your shutter speed would be about 1/50 sec. However, adjusting shutter angle can also be used creatively to produce a specific effect.

What are shutter angles above 180° used for?

Shutter angles above 180° increase motion blur because each frame is exposed for longer. This can make movement feel smoother, softer and sometimes more dreamlike. Higher angles tend to suit slower, more atmospheric scenes, such as mist drifting through woodland, animals moving gently through grass or fireflies glowing in the dark. Be careful, though, as too much motion blur can make fast action look smeared and cause fine textures to lose detail.

What are shutter angles below 180° used for?

Shutter angles below 180° reduce motion blur because each frame is exposed for less time. At 90°, movement looks noticeably sharper, while at 45° it can appear very crisp and staccato. This suits fast action or moments where you want to increase impact and intensity, such as a bird taking off or animals running. It can also work for dramatic or slightly comedic moments, where the choppier look adds character. Just be careful not to overuse very low angles, as too little motion blur can make footage feel unnatural, especially during panning. In addition, because less light reaches the sensor, you may also need to raise ISO or widen your aperture, which can increase noise or reduce depth of field.

How do I set a shutter angle on a Nikon camera?

First, you’ll want to choose your frame rate based on the subject and the look you want. For natural motion, 25fps is a good starting point. If you want the option to slow footage down on a 25fps timeline, 50fps or 100fps are useful choices, as they divide evenly and give smooth slow motion.

Next, set the shutter angle, opting for 180° if you want a natural, consistent look. On supported cameras, including the Nikon ZR, Z6III, Z8 and Z9, you can switch from shutter speed to shutter angle in the video settings using ‘Shutter’ mode. Once selected, shutter speed is shown as an angle rather than a fraction of a second.

Then adjust aperture for creative intent. If there is too much light, such as when filming in bright conditions, you can use a variable ND filter to reduce exposure without changing your shutter angle or aperture. Finally, fine tune ISO to balance exposure while keeping noise under control.

To keep things consistent across your footage, avoid changing shutter angle unless you want a deliberate stylistic shift. It’s best to treat it as a creative constant, adjusting the ND, aperture and ISO around it as conditions change.

Can I fix shutter angle mistakes in editing?

It’s very difficult to fix shutter angle mistakes in editing, as they’re baked into the footage. If your shutter angle was too narrow and the footage looks overly sharp, you may be able to improve it by adding motion blur in post. If your shutter angle was too wide and there is too much motion blur, it’s much harder to correct. Once that blur is recorded, the lost detail can’t really be recovered, so it’s important to prioritise getting it right when filming, rather than planning to fix it later.

Shutter angle top tips

1. Stick with 180° for most of your work to produce natural-looking, cinematic motion.
2. Keep shutter angle fixed so that when you change frame rate motion blur stays consistent without you needing to constantly adjust settings.
3. Choose frame rate based on the subject and situation you are filming. For natural motion, 25fps is a good starting point, but if you want slow motion on a 25fps timeline, try filming at 50fps or 100fps.
4. Use ND filters to control exposure, as they reduce the light entering the lens and allow you to keep your shutter angle and aperture where you want them.
5. Have fun with it! Experiment with shutter angle deliberately to create interesting effects in different situations.
