where digital and 35mm slr advantages converge the sd9 features three metering methods for greater control of photography s essence light 8 segment evaluative metering this metering mode offering exposure control with minimal error divides the screen into 8 independently metered segments whose data is comprehensively evaluated for optimal exposure setting excellent for shooting front-lit scenes as well as backlit high-contrast and other special situations 8-segment evaluative metering helps to reproduce brightness to a photographer s liking center area metering in this mode the camera meters only an area of about 5mm in diameter in the center of the screen this minimizes the influence of perimeter light sources so you can establish a highly specific area for determining the level of exposure that suits your purpose center weighted average metering in this most common metering mode the camera primarily meters the subject in the center of the screen while giving some weight to perimeter brightness exposure can be effectively controlled by using this mode in conjunction with the exposure compensation function names of parts c-dial command dial shutter button metering mode button function button af mode button b display panel names of display panel parts shutter speed aperture value counter iso sensitivity sound setting metering mode remote control mode iso sensitivity setting exposure meter auto bracketing µ auto white balance ¸ af mode ¹ battery indicator resolution exposure compensation and auto bracketing resolution button before you shoot exposure compensation lets you adjust exposure in 0.5ev steps within a ±3ev range of deviation from the autoexposure level set for the scene in situations where it is difficult to determine proper exposure such as when there are subtle differences of subject brightness it s a good idea to use auto bracketing to take three consecutive photographs at slightly different exposures so you can later choose the best-exposed shot self-timer 2s 10s mirror lock up auto bracketing iso sensitivity button diopter adjuster hot shoe exposure compensation button ae lock button b d-dial drive dial continuous shooting single frame shooting power off b s-dial shutter dial mode lever manual exposure shutter speed priority ae aperture priority ae program ae lens mount dust protector depth of field preview button remote control sensor eyepiece cup cf card access lamp zoom controller camera strap eyelet main menu button cf card cover view button connector cover information button modify menu button lens release button delete button cf card cover release lever 4-way controller battery case lock knob release socket color lcd monitor ok button cancel button 4 exposure modes to suit any situation p program ae this mode covers most shooting circumstances automatically setting a combination of shutter speed and aperture appropriate to the subject s brightness so you can shoot spontaneously without missing a moment or adjusting exposure a aperture priority ae set a desired aperture value and the camera determines the appropriate shutter speed stop down to increase depth of field open up to blur the background and emphasize the subject aperture priority ae is useful for achieving these and various other effects s shutter speed priority ae set a desired shutter speed and the sd9 selects the appropriate aperture value for subject brightness freeze action by selecting a fast shutter speed capture a blur of motion with a slow shutter speed or achieve various other effects using shutter speed priority ae m manual exposure this mode lets you set the shutter speed and aperture value as you choose as when you want to fix the exposure by referring to the ttl exposure meter external light meter etc this is particularly convenient for maintaining an exposure setting for several shots tripod socket battery latch power pack contact cover
