Taking a picture of a fast-moving subject In the Tv (Shutter priority) mode, you can stop the moving subject or blur as it passes across the viewfinder by using different shutter speeds. The aperture value is automatically set to give the appropriate exposure depending on the shutter speed. The following images show that the fast shutter speed (1/250 sec) captures a stop motion of moving subject, and the slow shutter speed (1/15 sec) captures a blurred image as the subject keeps moving until the shutter closes. Tv (Shutter Priority) Mode 1. Rotate the Mode dial ( ) to select Tv. ▲ Tv Mode, Aperture: f = 4, Shutter Speed: 1/250sec ▲ Tv Mode, Aperture: f = 16, Shutter Speed: 1/15sec 2. Turn the front dial ( ) and adjust the shutter speed. - The shutter speed and aperture value are displayed in the viewfinder and on the LCD panel. 3. Now, you are ready to take some pictures. Exposure Warning If the subject is too bright or too dark, the aperture value will blink in the viewfinder and on the LCD panel. If the subject is too bright, choose a faster shutter speed. If it is too dark, choose a slower shutter speed. When the aperture value indication stops blinking, you can take the picture with proper exposure. Use an ND (Neutral Density) filter if the subject is too bright. Use a flash if it is too dark. 083
