MANUAL FLASH AND POWER RATIO

The output of the flash can be specified when using manual flash control with power ratios.

Set the flash-control option in section 2 of the recording menu to manual. The power ratio, also in section 2, can then be selected. See page 64 for menu operation.

INSTANT PLAYBACK

After an image is captured, it can be displayed on the monitors for two, five, or ten seconds before being saved. When using continuous-advance bracketing, an index display is used. Instant playback is activated and the length of the playback period is set with the instant-playback option in section 3 of the recording menu (p. 64).

When the camera flash is raised, the power ratio is displayed on the monitor.

Power ratio

The setup option below instant playback specifies the display format:

The chart lists approximate guide numbers for manual flash calculations. The following equations are useful in determining the guide number, aperture (ƒ-number), or flash-to-subject distance required for exposures.

Image & information

 

Image & histogram

After each image is captured, it is displayed as specified by the menu. Press the shutter-release button partway down to end the instant playback.

During the instant playback period, the captured images can be deleted using the delete button (p. 36). When a continuous-advance bracketed series is captured, the entire series is erased. Single non-RAW images can be enlarged with the magnification button. The image is centered on the AF area used, see page 38 for information on enlarged playback.

NOISE REDUCTION

This function reduces the affect of dark noise with exposures of one second or longer. Processing is applied to each image after it is captured. The monitor remains blank during processing for a maximum of 30 seconds. This can be turned off in section 3 of the recording menu (p. 64). Noise reduction uses dark-frame subtraction. Noise reduction is not applied to a series of continuous- advance images
