Icon Setting Tv SHUTTER PRIORITY Av APERTURE PRIORITY Description Lets you select the shutter speed in Live View using the buttons, while the camera selects the appropriate aperture setting. This allows you to create special effects using the shutter speed (such as blurring the moving water in a stream). Lets you select the aperture setting (F-number) in Live View using the buttons, while the camera selects the appropriate shutter speed. This allows you to control the depth of field (for example to blur the background). 2-second release priority When the exposure mode is set to ACTION, you can take multiple pictures in rapid succession without having to wait for the camera to measure focus and exposure for each picture. Release and then re-press the Shutter button all the way down within 2 seconds after taking a picture, and the camera takes the next picture using the same focus and exposure measurements as the previous picture. Noise Reduction for Long Exposures At longer shutter speeds the camera will automatically take a second exposure with the shutter closed in order to measure and reduce the noise (grainy look) in the image. In these cases, the exposure will seem to take twice as long as expected. For example, in a 1-second exposure, the active display will stay dark for 2 seconds until the noise reduction frame is exposed. This means that at longer shutter speeds, you may not be able to take quite as many shots back-to-back. Chapter 2: Taking Pictures and Recording Video Clips 39

2-second release priority
When the exposure mode is set to
ACTION
, you can take
multiple pictures in rapid succession without having to wait for
the camera to measure focus and exposure for each picture.
Release and then re-press the
Shutter
button all the way down
within 2 seconds after taking a picture, and the camera takes
the next picture using the same focus and exposure
measurements as the previous picture.
Noise Reduction for Long Exposures
At longer shutter speeds the camera will automatically take a
second exposure with the shutter closed in order to measure
and reduce the noise (grainy look) in the image. In these cases,
the exposure will seem to take twice as long as expected. For
example, in a 1-second exposure, the active display will stay
dark for 2 seconds until the noise reduction frame is exposed.
This means that at longer shutter speeds, you may not be able
to take quite as many shots back-to-back.
