Setting the shutter priority mode is very, very simple with this camera; it is right here on your mode dial. Just change this to TV. TV stands for time value and that means shutter priority, which means I get to control the shutter speed and the camera will compensate by selecting the most appropriate aperture.
The reason you might want to control the shutter speed is to maintain a fast shutter speed, to stop moving subjects. So for example, if you’re taking pictures of sports you can use this mode and set the shutter speed to one over 500 or faster in order to stop the action.
To change the shutter speed in this mode, just use your dial right here next to the shutter button. Remember this mode does allow you to use the flash but if you use the flash, you won’t be able to select anything faster than one over 200 of a second. So for sports photography, it’s recommended not to use the flash and to set the a shutter speed fast enough to stop your moving target, also for sports photography it is recommended to use the continuously drive mode. So if that is your intention, press the drive mode button right here and move over to select the continuously shooting.
Press set, now I have a fast shutter speed and as long as I hold the shutter button down, the camera will continue taking pictures and that will make it much easier for me, to capture the image I intended. Because you cannot use the flash with flash shuttered speeds, your alternative is increasing the ISO. So if I press my shutter button half way you will see that the aperture selected is blinking and that means that I am not letting in enough light with the selected shutter speed.
So what I can do is increase the ISO to increase the sensitivity of the camera to the available light. Press the ISO button and increase that to 1600 press set, and now if I press the shutter button half way you can see that the aperture selected is 5.6, it is no longer blinking at me and now we will have a well exposed picture.
