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.

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.

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.

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.

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.

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.

Weak

Medium

Strong

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.

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.

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*.
