USING SHUTTER PRIORITY (TV) MODE TO STOP MOTION In Chapter 3, “Camera Shooting Modes,” you learned about the different shooting modes offered by the 60D. Tv mode gives you full control over the shutter speed— you pick the shutter speed and the camera determines the aperture. In many instances of sports and action photography, you will be working with very fast shutter speeds, and using the Tv mode will give you the control you need to capture high-speed images (Figure 6.4). In order to use a fast shutter speed, you need to be in an environment with sufficient light available for the speed you want to use. You might decide to set your aperture at a wide f-stop in order to bring more light into the sensor to balance the fast shutter speed. However, there may be times when your environment is just too dark for what you want to shoot—you’ll know this because the aperture value will flash on the top LCD Panel and also on the viewfinder info screen. When the light is insufficient for the shutter speed and aperture combination you want to use, you’ll need to change your ISO settings.
FIGURE 6.4 I used a fast shutter speed to capture the expression of this little girl as she was jumping.
