Shutter speeds faster than about 1/250th (varies depending on camera) do not give the flash time to fire before the shutter starts to close. The flash fires, then a second curtain follows the first to end the exposure. When the shutter button is pressed the first of two curtains opens.

ISO 100) because the image quality is better, and only raise it when working in low levels of light. The photographer will usually use the lowest ISO possible (e.g. There is a third variable, the ISO speed, which affects exposure. 1/2000th sec) or blur (1 sec) moving action the photographer will instead first select the shutter speed and let the camera select the aperture needed for correct exposure (Tv mode). f/2.8) to make the subject contrast and allow the camera to select the shutter speed needed for correct exposure (Av mode). f/11) or keep the subject sharply focused but blur a distracting background (e.g. depth of field) to keep both the subject and background sharp (e.g. Most frequently the photographer will first select the f/stop needed to produce the desired depth of focus (i.e.
Together the speed of the shutter and the aperture are used to control exposure for creative purposes. Memorize those numbers if you have not already.

Some think a click of the adjustment wheel from say f/8 to f/9 is a full stop when it is actually 1/3 stop. What confuses some neophytes is that today's digital cameras allow adjustments in 1/3 stops.

Although few f/1 lenses have ever been made, that is were the series starts. All that is really necessary is to learn the progression of f/stops which cut the amount of light in half with each incremental step. The f/system was devised so a photographer didn't need to worry about such details. The f/number for an aperture is actually the actual diameter of the opening divided by the focal length of the lens. If you want to see what the aperture in your lens looks likes set it in M mode to f/16 and 1 second, look into the lens and press the shutter. If we look into a lens the aperture will not be seen because digital cameras keep it retracted in the fully open position at all times except when the image is actually being recorded. In the middle of every lens there is an adjustable aperture which controls the amount of light which reaches the sensor. During the exposure the viewfinder is blacked-out by the camera mirror. The camera determines how to expose based on light measured on the viewfinder before the shutter is opened. The camera CMOS sensor doesn't dump the buckets to record the data until after the shutter closes. The rub, as they say, is that the camera can't see the buckets filling up to turn off the tap by closing the shutter. Those in the highlights fill very rapidly. Those in the shadows of the image fill slowly. Not all of pixels get filled at the same rate. When the shutter of the camera opens and exposes the sensor to light photons fill the pixel buckets. The goal of this tutorial is to explain the difference and they affect the operation of the Canon flashes.Ī pixel (sensor site) of a digital camera is very much like a bucket. The newest generation (since the 20D) have ""E-TTL-II" metering.
Canon used "TTL" to describe the metering system it is film cameras, then designated the metering in early digital cameras as "E-TTL". Through The Lens metering, of TTL is a generic term used to describe any camera which uses an internal metering system to control exposure in an automatic or partially automatic way.
