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:
“There are many things children accept as “grown-up things” over when they have no control and for which they have no responsibility—for instance, weddings, having babies, buying houses, and driving cars. Parents who are separating really need to help their children put divorce on that grown-up list, so that children do not see themselves as the cause of their parents’ decision to live apart.”
—Fred Rogers (20th century)
