How to FREEZE a fast -mov­ing sub­ject

It’s not just the speed of your sub­ject that counts, it’s where you stand and the an­gle you shoot from, too

01 Head­ing straight at you

If you shoot your sub­ject head-on there’s no move­ment across the frame at all, only move­ment to­wards the cam­era, so a shut­ter speed two to three times slower is of­ten pos­si­ble. It be­comes more of a fo­cus­ing prob­lem than a shut­ter speed is­sue – you need to get your cam­era’s aut­o­fo­cus sys­tem set up cor­rectly.

02 Mov­ing across the frame

This is where your sub­ject’s speed across the frame is high­est. If you check our ta­ble be­low you’ll see that a high shut­ter speed alone won’t al­ways be enough to get a sharp shot – you will need to pan with your sub­ject too.

03 45-de­gree an­gle

Your sub­ject might be trav­el­ling at ex­actly the same speed as it was when seen side-on, but its speed across the frame will be halved. This means you can use a shut­ter speed half as fast to freeze its move­ment, and it will be eas­ier to keep your sub­ject cen­tred in the frame. It’s now mov­ing to­wards the cam­era, though, so the aut­o­fo­cus will need to keep up.

The key fac­tor with mov­ing sub­jects is their speed across the cam­era frame, not their speed in real life.
