The Three pillars of exposure

Aperture

F/2.8

F16
















1) the aperture is related to the pupil.

2) The smaller the aperture the higher the f-number, the higher the aperture smaller the f-number.

3) The aperture impacts the depth of field because, the depth of field is the area of the image that appears sharp. The sharpness of the photo depends the aperture setting.

Shutter

Slow Shutter

Fast Shutter












If I were shooting at the beginning of blue and gold night, while
the sun is still partially up and the courtyard has reasonable light
the shutter speeds I would use for each of the following..

~ dunking booth... fast
~ food eating contest... slow
~ rock climbing wall... slow
~ someone working at the booth... slow
~ DJ in middle circle... medium
~ Diamond performance... fast

towards the end when there is no sun and it is dark
so there is not enough light to see from one end of the courtyard to the others.

~ dunking booth... slow
~ food eating contest... slow
~ rock climbing wall... slow
~ someone working at the booth... slow
~ DJ in middle circle... slow
~ Diamond performance... slow

There are three settings your camera has regarding shutter speed...

~ Aperture Priority - you set the lens while the camera sets the shutter speed
~ Shutter Priority - you set shutter speed and the camera sets the aperture
~ Manual - you set shutter and aperture

~The advantages of shooting with a higher ISO rate at a midnight football game are.. its perfect to use because there is not enough light, and we are using it to capture ultra fast shoots.
~The author suggested to always stick to a low ISO and us when there is plenty of light. There are times when you use low ISO in dark environments.
~ The author suggested to use an higher ISO when there is not enough light or when your shooting indoor with flash. Use during ultra fast shoots.

F/4 - at 1/25 of a sec. shutter speed looks better faces sharp. The background is blurry.
F/5.6 - at 1/250 , 1/60 , 1/125 of a sec. shutter speed looks best. the faces are clear and the background is still blurry.
F/11 - at 1/60 of a sec. shutter speed looks best. The background is clear.
F/16 - at 1/ 30 of a sec. shutter speed is better. The background is clear but a little darker.
F/22 - at 1/15 of a sec. shutter speed is OK looking. The image is dark and the faces are blurry.

The people in the photos, are always blurred when using slow shutter speeds.

The lowest shutter speed a photographer can hand-hold without a tripod, is 1/10 of a second.


I did OK on the tests. have a better understanding of Aperture, Shutter Speed, and ISO.
