Exposure Control
Light metering consisted of full-aperture through-the-lens metering, using a six zone silicon photocell. Automatic exposure settings were calculated using three metering modes: partial metering (central 6.5% of the picture), centre-weighted average metering and evaluative metering. The current metering mode was displayed on the LCD panel.
The Command Dial gave the photographer the choice of several shooting modes. The operation, and even the symbology used, would eventually be incorporated into Canon's digital camera range. Canon's fully automatic Programmed Image Control modes were Full Auto, Portrait, Landscape, Close-up and Sports.

The manually adjustable shooting modes were Shutter-priority, Aperture-priority and Depth-of-field. In these modes, the exposure could be compensated by ±2 stops in 1/2-stop increments. Also, AEB (auto exposure bracketing) could be used to take three continuous exposures in sequence, again by ±2 stops in 1/2-stop increments.
All exposure control settings would be ignored when the Command Dial was set to manual. Then, both shutter speed and aperture could be set independently. The viewfinder would still give information on whether the camera thought the shot would be under- or over-exposed, but it wouldn't interfere.

Famous quotes containing the word control:
““Have we any control over being born?,” my friend asked in despair. “No, the job is done for us while we’re sleeping, so to speak, and when we wake up everything is all set. We merely appear, like an ornate celebrity wheeled out in a wheelchair.” “I don’t remember,” my friend claimed. “No need to,” I said: “what need have us free-loaders for any special alertness? We’re done for.””
—Marvin Cohen, U.S. author and humorist. The Self-Devoted Friend, New Directions (1967)
