Exposure

Aperture-Speed-ISO

As we've seen, there are three parameters that affect the quantity of light captured in the image. If, in order to freeze the image of a running kid, I want to use a faster speed of 250 instead of 60, I'll have to compensate with aperture (from f/5.6 to f/2.8) or ISO (from ISO 200 to ISO 800).

The following table presents various options for aperture, speed and ISO that deliver images with the same exposure (the same amount of light).

aperturespeedISO
5.6 60 200
5.6 30 100
5.6 125 400
4.0 60 100
8.0 60 400
4.0 125 200
2.8 125 100
2.0 250 100
1.4 500 100


In order to know which parameter we want to change in any situation, we'll have to know in which other ways each one of them affects the image; mainly:
* shutter speed freezes movement
* aperture controls the depth of field (we'll see it here)
