FACE DETECTION SELF-TIMER* This advanced feature lets you join your group picture while maintaining precise exposure and focus. The Face Detection Self-Timer "counts" faces in your scene. When it detects an additional face, focus and exposure is automatically reset and the self-timer begins counting down. BLINK DETECTION Blink Detection lets you know right away whether one of your subjects blinked. If closed eyes are detected, a "blink warning" icon appears for 3 seconds so you can re-shoot while your subject or group of subjects is still in place. MULTI-POINT AiAF* Canon's wide-area AiAF automatically selects one or more focusing points based on the position of the subject within the frame. This allows you to quickly and accurately focus your shot under a wide variety of shooting conditions, even when the subject is not centered. AF POINT ZOOM* Turn on the AF Point Zoom feature to see an enlargement of the focus position when you press the shutter halfway for focus (when Face Detect AF or one-point AF is in use). This feature makes it easy to capture the perfect facial expression of your subject, or check for precise focus in macro shots. AF FRAME SIZE MODIFICATION* AF Frame Size Modification lets you reduce the size of a single AF point, for even more precise focus. Some models also allow the nine-point AiAF cluster to be reduced in size, and moved freely around most of the picture area, as shown below. Reduced AiAF frames move quickly between positions 9-Point AiAF Small Multi-Point AiAF FLEXIZONE AF/AE* Using FlexiZone AF/AE, you can freely move a single AF point around the frame. This lets you easily focus on off-center subjects without reframing the shot. When spot metering is selected, you can measure exposure at the chosen AF point or at the center of the frame. With this information, you can handle difficult lighting situations like a pro. SAFETY SHIFT & SAFETY FE* In Av and Tv modes, a Safety Shift function is available to eliminate exposure errors: the camera will automatically change shutter speed or aperture to achieve proper exposure for the given brightness conditions. Safety FE makes automatic adjustments to prevent over- or under-exposed flash shots when shooting in manual mode. SAFETY MF (MANUAL FOCUS)* After focusing the camera in manual focus mode, simply depress the shutter button halfway and the camera will automatically perform a fine adjustment for perfect focus. Safety MF can also be disabled for complete manual control. 40 PowerShot Technology EXPOSURE METERING Advanced photographers can select one of three light-metering modes: evaluative metering, center-weighted average metering, or spot metering. With some models, spot metering can also be linked to the AF point, and moved around the picture area. Shooting Function ISO SETTING Canon's advanced DIGIC Image Processor enables a range of ISO equivalent settings from 80 to 1600, achieving excellent image quality under darker conditions without a flash. With camera shake greatly reduced, you can shoot high quality images in many more situations. On the PowerShot G10, ISO settings are quickly accessible from a dedicated control dial. Evaluative Metering Spot Metering EXPOSURE COMPENSATION & FLASH EXPOSURE COMPENSATION* With Exposure Compensation and Flash Exposure Compensation, you can adjust the exposure and/or flash output above or below the level the camera automatically selects by up to ±2.0 stops in 1/3-stop increments. This is particularly useful for shooting situations that are difficult for the camera's automated sensors to meter correctly, such as subjects that are unusually light or dark in color. MANUALLY ADJUSTABLE FLASH* PowerShot cameras allow you to manually change the flash strength to perfectly suit your needs. Set the flash strength to one of 3 levels - weak, medium or strong. HIGH ISO AUTO* High ISO Auto allows the camera to select a wide range of ISO settings automatically, depending on the subject and scene. With Canon's latest Motion Detection Technology, it's even more advanced - it also factors in camera or subject movement when setting ISO automatically. AUTO ISO SHIFT* While sensitivity should in general be kept as low as possible for maximum image quality, too low a setting can cause camera shake and blurry photos. PowerShot cameras with Auto ISO Shift instantly maximize sensitivity for the given light, either automatically or at the push of a button. It minimizes camera shake, without the need to change the setting manually. The feature keeps you in creative control, allowing you to specify parameters for an ISO shift, or be notified when sensitivity is adjusted automatically. Weak Medium * Not on all models. Strong RED-EYE CORRECTION New technology combines with Face Detection to allow select PowerShot cameras to detect and remove red-eye, as images are played back on the LCD monitor. Some models even can detect and remove red-eye as photographs are taken*. 41 PowerShot Technology
