Explaining how to calculate Aperture,Shutter Speed, and ISO
So this is how you use the manual exposure settings
Aperture's
How much light enters the camera
1.4 / 2.0 / 2.8 / 4 / 5.6 / 8 / 16 / 22 / 32
Shutter Speed's
How fast your shutter opens and closes (in [fractions of] seconds)
1/1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1,000
ISO's
How sensitive your camera is to light*
100,200,400,800,1600,3200,6400,12800
*A higher ISO means higher grain
Examples
Let's say you get a reading of 1/4 shutter speed at F 8.0 and ISO 200. If you want to increase the shutter speed, you either have to increase the ISO or aperture to compe
