Giving priority to shutter speed (shutter-priority: Tv) Use this program to let you select the shutter E speed. Tv 1000 The camera sets the appropriate aperture (F number) automatically to give the correct Tv exposure. High shutter speeds are perfect for recording fast moving subjects (such as sports action) when you want to play back videos frame by frame, free from blur caused by the movement. But remember, in normal playback, fast moving subjects may appear to "strobe" (move jerkily). You can also choose slow shutter speeds (1/30, 1/15 and 1/8 of a second) for dramatic effects, such as a "streaming" background when panning, and for shooting in low- light conditions. When you turn the program selector to Tv the current shutter speed is show in the display. Select your desired shutter speed by turning the Av/Tv CTRL. You can choose shutter speeds of between 8 and 2,000. For a faster shutter speed, select a higher value. Notes: • The image quality may suffer slightly if you use slow shutter speeds for low- light conditions, and the autofocus may have not give accurate results. • When recording in extreme low-light conditions, we recommend the use of a Canon Speedlite or Video Light (available as optional accessories, see page 66). • When shooting using the Tv program, if the shutter speed display flashes the camera has not been able to set the exposure correctly. In such a case, change the setting so that the display stops flashing and lights up continuously. Using the Full Range of Features 37
