Program AE

Use the program AE mode to have the camera automatically set the shutter speed and aperture value to match the brightness of the scene.

zThe shutter speed and aperture value will show in red on the LCD monitor when the correct exposure cannot be obtained. Use the following methods to obtain the correct exposure and make them appear in white.

•Use the flash

•Change the ISO speed setting

•Change the metering mode

Differences between the P and Modes.

zThe following settings can be adjusted in P

mode, but not in mode.

• Exposure Compensation	• White Balance
• ISO Speed	• Flash (Flash on)
• AF frame selection	• Photo Effects
• Continuous Shooting	• Metering Mode
• Manual Focus

zFor the correlation between aperture value and shutter speed, see page 78.

Setting the Shutter Speed

When you set the shutter speed in the shutter- speed priority AE mode, the camera automatically selects an aperture value to match the brightness. Faster shutter speeds allow you to catch an instantaneous image of a moving subject while slower speeds create a flowing effect and allow you to shoot without a flash in dark areas.

zIf the aperture value shows in red, the image is underexposed (insufficient light) or overexposed (too much light). Adjust the shutter speed using the or button until the aperture value display turns to white.

zThe nature of CCD image sensors is such that noise in the recorded image increases at slow shutter speeds. This camera, however, applies special processing to images shot at shutter speeds slower than 1.3 seconds to eliminate the noise, thereby producing high-quality images. Nevertheless, a certain amount of processing time may be required before the next image can be shot.
