Canon EOS Digital Rebel Брошура та технічні характеристики

BASIC FEATURES

FLEXIZONE AF/AE

Using FlexiZone AF/AE, you can freely move the

AF point around the frame. Now you can easily

focus on off-center subjects without reframing

the shot. When spot metering is selected, you

can choose to measure exposure at the chosen

AF point or at the center of the frame. This option

gives you maximum flexibility, enabling you to

handle difficult lighting situations like a pro.

HYBRID AF SYSTEM*

This advanced Canon AF system combines the

best of two different autofocusing methods. An

external metering (triangulation) method is

used to perform initial general focusing. This is

immediately followed by the more traditional

TTL (contrast detection) method to fine-adjust

the focusing. This yields both speed and precision

of autofocusing that cannot be achieved with

either method alone.

INTELLIGENT ORIENTATION

SENSOR

By automatically sensing whether the picture

is being taken horizontally or vertically, PowerShot

cameras are able to avoid the typical errors that

occur in auto focus, auto exposure, and auto

white balance with less sophisticated cameras.

Moreover, pictures are properly oriented during

playback, whether on the camera's screen or a

computer monitor.

Horizontal

Vertical

WHITE BALANCE

Canon iSAPS technology ensures fast, accurate

automatic white balance compensation.

PowerShot cameras also let you select from preset

modes covering common lighting conditions,

for example, daylight, cloudy, tungsten, or

fluorescent. You can even perform a manual

white balance using a white reference target,

storing the measurement as a custom setting

for later recall.

Indoor Light

Daylight

ISO SETTING

Canon PowerShot cameras give you a choice

of ISO equivalent settings. As with film, the

lowest ISO setting possible for the shooting

conditions will yield the best image quality.

In most shooting modes, the camera will

automatically select the best ISO setting to

suit the conditions. However, in manual and

advanced shooting modes, you can set the

ISO to 50, 100, 200, or 400.

NOISE REDUCTION

Canon's exclusive

Imaging Processor

≥

performs advanced, highly precise data

computations that enhance resolution without

increasing noise, shattering the commonly held

notion that noise in a digital camera can only

be reduced at the expense of resolution. This

new anti-noise/ high-resolution processing

technology enables PowerShot cameras to

capture images of extraordinary quality, easily

surpassing the performance of other digital

cameras relying on general-purpose image

processing IC's.

BASIC FEATURES

RAW MODE CAPABILITY *

The exclusive

≥

Imaging Processor also

makes possible a RAW mode recording option.

While the multiple JPEG modes maximize image

quality and storage efficiency, you now have

the option of saving your photos in the RAW

format when you want to capture at the highest

possible quality with no compression.

METERING OPTIONS

Canon PowerShot cameras give advanced

photographers a choice of light-metering

modes for maximum exposure control:

evaluative metering, center-weighted average

metering, or spot metering. The spot metering

mode provides an exceptional degree of

control, enabling the measurement to be

tied to the AF point or fixed at the center

of the frame. It makes it easier to deal with

challenging lighting conditions or achieve

creative exposure effects.

PHOTO EFFECT MODE

For advanced creative effects, try one of the

Photo Effect Mode settings. Vivid Color yields

vibrant shots with dramatic high-contrast.

Neutral Color produces images of subtle,

elegant tonality. Low Sharpening softens an

image to create a romantic, soft-focus filter

effect. Sepia recreates

the look of vintage

photographs. Black

and White delivers

enhanced clarity –

especially useful

when shooting text.

Sepia

SAFETY SHIFT*

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 work within the ambient brightness

conditions.

FLASH OPTIONS

Multiple modes give you full control over flash-

assisted shooting. You can turn the flash and

auto red-eye reduction on and off in any

combination. You can even choose "first

curtain" or "second curtain" sync. Flash

strength can also be set manually to any of 3

levels. * You can also turn off the pre-flash to

avoid false tripping of external slave flashes.

First Curtain Sync

Second Curtain Sync

ADOBE RGB*

Because PowerShot cameras' professional-level

quality produces images that are ideal for use

as originals for printed documents, the camera

offers an expanded Adobe RGB color space set-

ting, the data standard of the printing industry,

in addition to a standard RGB color space setting.

* Not on all models.
