Shutter speed . Shutter speed is the amount of time that the digital sensor (or film, for those of old enough to remember) is exposed to light to capture the image. Fast shutter speed, takes the image almost instantly as in frozen in time. Fast shutter speeds (such as 1/2000th of a second) are especially useful in bright light or when trying to capture photos of things that are moving fast, such as athletes and wildlife. When using a slow shutter speed it’s also a good idea to use a tripod and remote shutter release to avoid camera shake. To really confuse the issue, many people refer to the ISO setting as the “speed.” This is another throwback to 35mm photography where we often talked about “film speed.” It’s best to avoid this nomenclature since “speed” is already overused to describe large f/stops (“fast, high-speed f/1.2 lenses”) and shutter speed. Use slow shutter speeds of at least 10 seconds or more for night shots of cities, buildings and streets etc. The number used in setting your shutter speed refers to the denominator of that fraction. These represented halving the amount of light one direction and doubling it the other. The camera calculates the f-stop. Each stop was either twice as long or half as much time. For film captured at 24 fps: Shutter speeds were like 1/30th, 1/60th , 1/125th, 1/250th of second. Film motion picture cameras use a rotary disc shutter to achieve their exposure times, with shutter speed indicated as a shutter angle. Be aware that these numbers do not equate to full seconds. Shutter speed is the amount of time that each individual frame is exposed for. Just like with the lenses “stops” the shutter also has stops. Shutter Priority: You choose the shutter speed and the ISO. When capturing video, shutter speed is the amount of time that each individual frame is exposed for. In video, this is typically a fraction of a second, like 1/48 sec or 1/60 sec. Ever wondered what the heck shutter angle is, how it compares to shutter speed, and if you should really care or not? The following constant settings were used for some parameters: Exposure is set to Physical Exposure, F-Number is 8.0, Shutter speed is 200.0, Film speed (ISO) is 200.0, and Vignetting is off. 1 is equivalent to 1 … White balance is white (255, 255, 255) They will typically read, in order, 1-2-4-8-15-30-60-125-250-500-1000-2000-4000 and possibly more. Program Mode: The camera chooses the best f-stop/shutter speed combination for the ISO of the film. Slow vs. Fast Camera Shutter Speed Unlike most things, this isn’t a question of either/or – slow versus fast doesn’t mean better versus worse. Note on DX Coding: Modern cameras can read the ISO of a film, thanks to the DX coding on the film cartridge. The majority of film cameras have multiple shutter speed settings on the shutter speed dial. So, if you set your shutter speed to 60, that means each frame is exposed for 1/60th of a second. In video, shutter speed is almost always in fractions of a second. There are so many numbers to keep in mind when filmmaking, and a lot of them look and sound the same: 24p vs 1080p; 1/30 shutter speed vs. 30 frames per second. Slower shutter speeds are good in low light when you need to let more light … In the old days (again) each shutter speed was a click stop.
