A shutter speed of 1 ⁄ 50 s with an f /4 aperture gives the same exposure value as a 1 ⁄ 100 s shutter speed with an f /2.8 aperture, and also the same exposure value as a 1 ⁄ 200 s shutter speed with an f /2 aperture, or 1 ⁄ 25 s at f /5.6. [citation needed]
Popular exposure chart type, showing exposure values EV (red lines) as combinations of aperture and shutter speed values. The green lines are sample program lines, by which a digital camera automatically selects both the shutter speed and the aperture for given exposure value (brightness of light), when set to Program mode (P). (Canon, n.d.)
Canon A-1 with a FD 50/1.8 Viewfinder of a Canon A-1. The right number is the current F-number (1.8), meaning that the aperture is fairly wide open. The left number (45) indicates the approximate shutter speed of 45 −1 s (the camera can select odd shutter speeds, but does not display them)
The shutter speed dial on the finder locked on to the camera's normal shutter dial and drove it through a coupling pin for the standard range of 1 – 1 ⁄ 60 s. [ 5 ] : 5–6 When the Booster's shutter speed dial was turned further, towards longer times, the camera's dial stopped at the B(ulb) setting, and the finder kept the shutter release ...
Accessories for the AE-1 include the Canon Winder A (motorized single frame film advance up to 2 frames per second), the Canon Databack A (sequential numbering or date stamping on the film), and the Canon Speedlite 155A (guide number 56/17 (feet/meters) at ASA 100) and Canon Speedlite 177A (guide number 83/25 (feet/meters) at ASA 100 ...
Guide number. A value indicating the power of an electronic flash apparatus, and used to estimate exposure. GN = distance × f-number. One needs to specify the film or sensor ISO speed, and it is conventional to quote for ISO 100/21°. The distance can be in feet or in metres, the units to be specified. [4] GND: Graduated neutral density. A ...
Shutter speeds range from 30 seconds to 1/8000 of a second in all exposure modes. A non-timed bulb speed is available. Flash X-sync is available up to a shutter speed of 1/250 of a second. There are 14 custom functions to change the way the camera operates, which set options like exposure steps and mirror lock-up.
The Canon EOS 6D is a 20.2-megapixel full-frame CMOS digital single-lens reflex camera made by Canon. ... 30 s – 1/4,000 s (and bulb) is the shutter speed range.
