A - APERTURE PRIORITY MODE

A-MODE FLASH

When the built in flash is up or an attached accessory flash is on, it will fire each time a picture is taken. The camera'sTTL control ensures a proper exposure.

•When the flash is ready, will appear in the viewfinder.

•The shutter will stay at or below the camera's top x-sync speed of 1/200. Faster shutter speeds can be used when high-speed flash sync is selected (p 87).

•A larger f-number will result in a smaller flash range.

•Push the flash down if it is not needed.

• If 200 blinks in the data panel and viewfinder, the f-number is too low and the photograph will be overexposed. Turn either dial to select a larger aperture number until the shutter speed stops blinking.

The size of the aperture (lens opening) determines the depth-of- field in the final image as well as the intensity of the light falling on the film. Depth of field is the area in front of and behind the point where the lens is focused which will appear sharp.

Large apertures (small f-numbers) limit the depth of field to a narrow range. Choose a large aperture if you want a defocused background so your main subject stands out, such as with portraits.

Small apertures (large f-numbers) provide greater depth-of-field. Choose a small aperture when you want maximum focus range, such as in a landscape photograph.

•In general, wider lenses provide more depth-of-field and longer (telephoto) provide less depth of field.

•There is less depth of field when your subject is close to the lens.
