Kylie is getting ready to shoot action photos of a horse race. What shutter speed would likely be ideal for this type of shoot in order to avoid blurry images?

1/200
1/50
1/500
1/250

To capture action photos of a horse race without motion blur, you will typically need a fast shutter speed. Horse races involve rapid movement, and to freeze the motion of the horses, you'll need to use a high shutter speed.

Out of the options provided:

1/200 - Might be usable for slower-paced action or if panning techniques are used.
1/50 - Too slow for fast action; will likely result in motion blur.
1/500 - This is a fast shutter speed and would be a good choice for freezing the action.
1/250 - May work for action shots but might not be fast enough to completely freeze the fastest moments in a horse race.

Therefore, 1/500 is the ideal choice for taking sharp action photos at a horse race to avoid blurry images. Depending on the lighting conditions and the speed of the action, you might even need to go faster, such as 1/1000 or higher, to ensure the horses are completely sharp. Always take into account the available light and adjust ISO and aperture settings accordingly to achieve a properly exposed photo with the desired shutter speed.
