webpage detailing F stops

fguihen · 2008-02-25 19:19:44

Im aware that each change in F value halves the amount of light comming into the camera ( for each full stop up or down), and the same applies for the exposure time. does anyone know of a website that lists if each stop ( both apature f stop and time value) are a full or half stop?

1 - 1.4 - 2 - 2.8 - 4 - 5.6 - 8 - 11 - 16 - 22 - 32 - 44 - 64 - 96 - 128 are full stops, anything else would be 1/3 increments. Times would run 1/4000 - 1/2000 - 1/1000 - 1/500 - 1/250 - 1/125 - 1/60 - 1/30 - 1/15 - 1/8 - 1/4 - 1/2 - 1.
