Photography - Foundation (Aperture, ISO, Shutter)

Aperture　f1，f1.4，f2，f2.8，f4，f5.6，f8，f11，f16，f22，f32，f44，f64
ISO 3200, 1600, 800, 400, 200, 100
Shutter 1', 30", 15", 8", 4", 2", 1", 1/2", 1/4", 1/8", 1/15", 1/30", 1/60", 1/125", 1/250", 1/500", 1/1000"


ex.
F1.4+ISO3200+1/30" = F11+ISO100+1'
F1.4 -> F11 = 6
ISO3200 -> ISO100 = 5
Aperture + ISO = Shutter
1/30"->1' = 11

下列各組合都是一樣的進光量

2 1/500
2.8 1/250
4 1/125
5.6 1/60
8 1/30
11 1/15
