Which setting would typically be adjusted to capture fast-moving subjects without blur?

To capture fast-moving subjects without blur, adjusting the shutter speed is crucial. The shutter speed determines the duration that the camera's sensor is exposed to light, and it plays a significant role in freezing motion. A faster shutter speed reduces the time that motion can cause blur and helps to capture sharp images of subjects in action, such as athletes or vehicles.

For instance, if a photographer wants to freeze the motion of a soccer player kicking a ball, a shutter speed of 1/500th of a second or faster would be ideal. This rapid exposure time minimizes motion blur caused by the subject’s movement.

While aperture and ISO can influence the overall exposure and image quality, they primarily affect depth of field and sensitivity to light, respectively, rather than directly addressing motion blur. White balance, meanwhile, relates to color temperature and does not impact motion or motion blur in any direct way. Therefore, for the purpose of capturing sharp images of fast-moving subjects, shutter speed is the key setting to adjust.
