How to freeze motion, with and without a flash

Freezing motion is relatively easy… Showing the details of what the eye cannot see in a split second is rather cool, and maybe the most exciting part of capturing moving subjects. I often work with performers so I am used to capturing movement, the idea here is to show you how to get great results by following a few basic rules.

So I assume you are shooting in manual mode!

Basically, there are 2 ways of freezing motion, with your shutter speed or your flash.

1/ When shooting outdoors, with the sun as your main light or in an environment with lots of light, your shutter speed will be the main ingredient to freeze your subject. I usually start at around 1/500s, keep my ISO as low as possible and start at a F stop around 5.6.

If you are using a flash use the HyperSync or High-Speed Sync mode of your flash to go beyond the 1/200 or 1/250 sync limit… If you don’t know what HSS or HS is:

I believe that going under 1/500s might not be enough to freeze movement. Depending on how fast your model moves, going above 1.500s will increase your chances of having a sharp image. Your ISO and aperture will depend on your tastes. For example if you wish to have a better background separation, simply use a low f stop but remenber, your are working with a moving subject. Using a narrow depth of field, makes it harder to nail focus.

If you are shooting indoors or at dusk and you don’t have a lot of light, don’t be afraid to increase your ISO. Having a high shutter speed will decrease the amount of light touching your sensor. I sometimes go up to ISO 3200 to compensate.

2/ When using your flash to freeze movement, keep your shutter speed at 1/200s or lower and let your flash do the job. The brief burst of light, the short flash duration, will be enough to freeze the action! So now we are o longer in HS or HSS mode, we rely on the short burst of light to capture movement.

Lets make it simple, how does your camera capture an image? Your shutter opens and closes, and while it’s open, your sensor captures light and creates your image.

I work with Broncolor lights, and when I use the “Speed” mode that enables short flash durations (check your gear to see how you can achieve this) , the flash can be as short as 1/19000s ! This means that if your camera is set at 1/200s after your flash has fired your shutter will still be open for a brief moment and it will continue to capture your photo and whatever is going on in front of your camera. 

So your success will depend on the available light. If the location you are working in is dark, if it is poorly lit, you will have great results. If there is a bit of light around, coming from any light source you might have motion blur in your image.

So The decision is up to you, are you willing to keep these blurry parts in your shots?

Here, by killing the ambient light, I manage to have the right balance to better freeze the action.

Don’t forget to play with your f stop and ISO to correctly expose and balance your shot.

I said earlier that under 1/500 might give you blurry results… I tried a few times and depending on the amount of light you let in you, and on how fast your subjet moves, you can still get great results with a slower shutter speed.

Letting motion blur in your shot is not a bad thing… I sometimes play with it, like in this shot where I didn’t want the ball to be tack sharp.

I said it before Aperture is an important element you cannot overlook. Outside having motion blur or not, you want a focused image. So using a high f stop will ensure a focused photo… I still use 2 simple techniques to focus on my subject:

A/ I decide where I want to catch my subject and set focus before the action. This demands a precise execution for both the photographer and the performer. I usually do this when I have a specific composition in mind, and when I work on a tripod.

B/ I use AI servo and follow my performer and blindly rely on the continuous autofocus of my camera.

So when do you use Flash, when do you use your shutter speed to freeze motion? Only you can answer this question. I choose the shutter speed often over my flash when shooting outoors and use my flash when I work indoors. But this is not systematic as every situation is unique and different.

Know exactly what you want to do, with or without flash, with a bit of motion blur, a lot or without, with a shallow or wide depth of field and so on… Then experiment, try, fail and repeat! You will find your style and feel confortable with time.

Have fun building your own creative tools!
