Canon A540 Operation
Canon A540 Operation
While the Canon A540's user interface may seem slightly cryptic at first, it's actually quite efficient. Most camera functions are controlled externally, and a few of the external control buttons serve multiple functions. When you do need to enter the LCD menu system, navigation is straightforward with only two main pages of options. That said, the majority of external controls do require the LCD display to be active. Regardless, the A540's external controls cut down on the amount of time spent searching menu screens, and I particularly like the "Function" menu which became standard on Canon digital camera models in the 2003 model year. Combined with the instruction manual, the A540's user interface shouldn't take more than an hour to get comfortable with.
Record Mode LCD Display: In Record mode, the A540's LCD reports various exposure settings, including camera modes, the resolution and quality settings, number of available images, etc. Half-pressing the Shutter button reports the aperture and shutter speed settings, in all modes except Manual. (Aperture and shutter speed are displayed continuously in Manual mode, whether the Shutter button is pressed or not.) Pressing the Display button cycles through the available display modes, including the image with information, no display at all, and the image only.
Playback Mode LCD Display: In Playback mode, the Canon A540's 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, 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 A540 Modes and Menus
Record Mode: Marked on the Mode switch with the red camera icon, this mode sets up the Canon A540 for capturing still and moving images. The following exposure modes are available:
- Auto: The camera controls everything about the exposure, except for Flash and Macro modes, and image size and quality settings.
- Program AE (P): Places the camera in control of shutter speed and lens aperture, while you maintain control over everything else (i.e., white balance, ISO, metering, exposure compensation, flash, etc.).
- Shutter-Speed Priority AE (Tv): Allows you to control the shutter speed settings from 1/2,000 to 15 seconds, while the camera controls the aperture. All other exposure settings are available.
- Aperture Priority AE (Av): Allows you to set the lens aperture from f/2.6 to f/8.0 (depending on the zoom setting), while the camera controls the shutter speed. In this mode, you maintain control over all other exposure variables.
- Manual (M): Provides complete control over all exposure settings, including shutter speed and lens aperture (available shutter speeds depend on the aperture and lens zoom 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 Scene: Uses slower shutter speeds and flash to even out nighttime exposures. The slow shutter speed allows more ambient light to be recorded in the low-light areas, while the flash fully exposes the subject.
- Scene: Accesses the remaining preset Scene modes, including Night Snapshot, Kids & Pets, Indoor, Foliage, Snow, Beach, Fireworks, Underwater, Color Accent, and Color Swap.
- Stitch-Assist: Allows you to record a series of images, either horizontally or vertically, to be "stitched" together into one large image or panorama on a computer.
- Movie: Records up to 640x480 pixels at 30 or 15 frames per second while space remains on the memory card.
Record Menu: Pressing the Canon A540's Menu button in Record mode pulls up the following options (not all options are available in all modes):
- AiAF: Turns the AiAF system on or off. If on, the camera judges focus based on the subject's proximity to nine focus areas arrayed in the center of the image. If off, the camera bases focus on the very center of the frame.
- Red-Eye Reduction: Turns the Red-Eye Reduction pre-flash on or off, which works with all flash modes.
- MF-Point Zoom: Turns the MF Point zoom option on or off. If on, the center of the frame is enlarged on the LCD display for better viewing while adjusting the manual focus.
- AF Assist Beam: Turns the AF Assist light on or off. If on, the light automatically illuminates in dark shooting conditions.
- Digital Zoom: Turns the 4.0x variable digital zoom on or off.
- Review: Turns the instant image review function on or off, with available image display times from two to 10 seconds in one second steps.
- Grid Lines: Turns a display of grid lines to align subjects in Record mode on or off.
- Date Stamp: Only available in Postcard mode (set via the Function menu), allows printing of Date or Date and Time on photo.
Playback Mode: This mode lets you review captured images and movies on the memory card, as well as erase them, protect them, or tag them for printing and transfer. The traditional green Playback symbol denotes this mode on the Mode switch. Pressing the Canon A540's Menu button displays the following options:
- Auto Play: Automatically plays all captured images in a slide show.
- Sound Memo: Records a short sound clip to accompany a captured image.
- Protect: Marks the current image for write-protection, or removes write-protection. Protected images cannot be deleted or manipulated, except through card formatting, which erases all files.
- Rotate: Rotates the current image 90 or 270 degrees clockwise.
- Erase All: Erases all files on the memory card, except protected ones.
- Transfer Order: Marks images to be transferred to a computer later.
