SLR Function

Portrait mode selects a wide aperture to blur the background of the subject. The pop-up flash is automatically controlled, while the Drive mode is set to Continuous shooting, the AF mode to One Shot, and the metering to Evaluative metering.

Landscape mode selects small apertures to maximize depth of field. This mode prevents the release of the flash, sets the camera to Single shooting and uses Evaluative metering. This mode can also be used to shoot a night scene as it offers a maximum 8-second exposure time.

Close-up mode works to balance the depth of field and the shutter speed, but with an overall preference for a shallow depth of field. This mode also controls the release of the pop-up flash, and uses Single shooting.

Sports mode optimizes the shutter speed so as to freeze action. The pop-up flash cannot be released, the Continuous shooting mode is activated, as is the AI Servo mode which allows the camera to track the subject and maintain focus using all 9 AF points

Night Portrait mode uses a longer exposure and flash to capture a well-lit foreground and a visible background. The flash is automatically opened and only the Single or Self-timer/Remote control drive modes are available. The mode automatically uses Evaluative metering, Single shooting and One Shot AF.

Flash Off mode prevents the flash from being opened automatically and can be used for interior shots, or long exposures (5-second maximum exposure time, controlled by the camera).

The Program mode chooses the most appropriate combination of shutter speed and aperture, and displays it in the viewfinder's display. Program Shift is also available, and another combination of aperture/shutter speed can be selected using the Main Dial .

Shutter Priority mode, Tv, provides access to the full shutter speed range of the EOS 30D: from 1/8000 sec to 30 seconds with the Main Dial , while the camera sets the aperture.
Aperture Priority mode, Av, allows selecting the aperture, using the Main Dial while the camera matches the selection to a shutter speed. The range depends on the lens in use. Depth of field preview is available by pressing on a button located on the lower left side of the lens mount of the body, beneath the larger lens release button.

Manual mode provides control over the shutter speed using Main Dial , and the aperture using the Quick Control Dial . The aperture range depends on the lens in use, the shutter speed range covers from 1/8000 second to 30 seconds, and adds a Bulb mode that is unlimited, and which can be used in conjunction with mirror lock-up, and a Long Exposure Noise Reduction option (see the Characteristics section of the review).

Automatic Depth of Field AE works much like the Program mode, but serves to obtain a wide depth of field between a near and a far subject, and is effective for group photos and landscape shots. The camera uses all 9 focusing points to determine the nearest and the farthest points in the frame and sets the aperture accordingly.
