Canon PowerShot A570 IS Operation
Despite Canon's proclivity for moving functions from menus to buttons and back again (not to mention moving buttons around), the Canon digicam user interface is both easy to remember and efficient to use. It does require a little study, but no more than any other sophisticated system. There are buttons for shot-by-shot control of things like EV, Flash and Focus settings while options like ISO, White Balance, Metering, Image Size and Resolution are just a press of the Function button away in the menu system.
Record Mode LCD Display: In Record mode, the LCD reports various exposure settings, including camera modes, the Resolution and Quality settings, number of available images, ISO, Drive mode, and Metering mode. Half-pressing the Shutter button reports the Aperture and Shutter Speed settings, in all modes except Movie. Pressing the Display button cycles through the available display modes, including the image only, image with information, and no display at all (for using the optical viewfinder in dark locations, for example).
Playback Mode LCD Display: In Playback mode, the LCD reports the image series number, Resolution and Quality setting, file name, and the date and time of image capture. Pressing the Display button once pulls up an enhanced information display, pressing twice will show a full information display with a histogram for checking the exposure. A third press cancels the information overlay entirely. The telephoto side of the zoom toggle lets you zoom in on a portion of the image, while the wide-angle side backs you out again, and lets you step out to an index view of captured images, displayed as nine thumbnails at a time. Zooming out one step past the point at which the index display appears adds a "jump" bar to the bottom of the screen, letting you jump forward or back nine images at a time, rather than scrolling from each image to the next individually.
Canon PowerShot A570 IS Modes and MenusRecord Mode: Marked on the Mode switch with the red camera icon, this mode sets up the Canon A570 IS for capturing still images or Movies. The following exposure modes are available:
- Programmed Auto (P): The camera sets the shutter speed and aperture automatically, but you can adjust exposure with the EV setting. You can also change the ISO, Flash mode and Metering mode to affect exposure.
- Shutter Priority (Tv): You select the shutter speed and the camera selects the aperture.
- Aperture Priority (Av): You set the aperture and the camera sets the shutter speed.
- Manual (M): Provides direct and independent control of the aperture and shutter speeds, a true manual exposure mode.
- Auto: The camera controls everything about the exposure, except for Flash and Macro modes, and image size and quality settings.
- Portrait: Uses a large aperture setting to blur the background and keep the primary subject in sharp focus.
- Landscape: Employs a small aperture setting to keep both the background and foreground in focus.
- Night Snapshot: Allows you to take snapshots of people against night backgrounds by reducing the effects of camera shake even without using a tripod.
- Kids&Pets: Offers a faster shutter speed for capturing fast moving little ones.
- Indoor: Reduces blur from camera shake and maintains a subject's true color when shooting under tungsten or fluorescent light.
- Scene: Accesses the remaining preset Scene modes, including Night Scene, Foliage, Snow, Beach, Fireworks, Aquarium, and Underwater.
- Stitch Assist: Allows you to shoot overlapping images that can be merged into a single panorama on the computer.
- Movie: Records 640 x 480 at 30 or 15 frames per second, 320 x 240 pixels at 60, 30 or 15 fps, and 160 x 120 at 15fps.
Record Menu: Pressing the Menu button on the Canon A570 IS in Record mode displays the following options (not all options are available in all modes):
- AiAF: Turns the 9-point AiAF system on or off or enables the Face Detect mode. When the AiAF system is on, the camera judges focus based on the subject's proximity to nine focus areas arrayed in the center of the image. When off, the camera bases focus on the very center of the frame. With Face Detect on, both focus and exposure are set by the face detection technology if a face is detected, otherwise the AiAF system will be used.
- Digital Zoom: Sets standard digital zoom, no zoom, or a zoom that starts at 1.5x or 1.9x, even when you're at wide angle. Not available in Wide Screen mode.
- Red-Eye Reduction: Turns the Red-Eye Reduction pre-flash on or off, which works with all flash modes.
- Safety FE: Enables or disables safety flash exposure, which adjusts shutter speed and aperture to protect highlights.
- MF-Point Zoom: Enables or disables a magnified view in the center of the LCD during manual focus.
- Safety MF: Enables or disables automatic fine focus after manual focus is set.
- AF Assist Beam: Turns the AF Assist light on or off. If on, the light automatically illuminates in dark shooting conditions to help find focus.
- Review: Turns the instant image review function on or off, with available image display times from two to 10 seconds in one second steps, or Hold to keep the image on until you press the shutter button or turn the camera off.
- Display Overlay: Toggles among a display of grid lines, a 3:2 aspect ratio mask (for framing 4x6 images), or both.
- IS Mode: Sets the Image Stabilization mode to be Continuous, Shoot Only, Panning, or Off.
