aperture, shutter speed, and iso

aperture

f-stop 2.8

f-stop 16

1. Aperture is very similar to the human eye. The pupil size increases and decreases, depending on the light of it's environment, letting an adequate amount of light in and out. 

2. The smaller the Aperture diaphragm, the higher the Aperture f-stop number. 

3. The depth of field can be affected by aperture in that the more light that is let in, the more secluded the foreground will be. Meaning, with more light, the less background is focused. 

shutter speed

fast shutter speed

slow shutter speed

fast vs. slow shutter speeds

shutter priority: shutter is manually selected, while aperture is automatically set

manual: aperture and shutter speed set manually

 iso

iso 3200

iso 200

1. The shutter speed has to be high to freeze the motion of the athletes, so the iso can be high, to let in light at a dark event.

2. The author said to always use a low iso when there is plenty of light, or else there will be ugly grain.

3. The author suggested using high iso when attempting to freeze motion without a flash or light.
