The Three Pillars Of Exposure: Aperture, ISO, Shutter Speed

APERTURE

F16



F2.8




1) The body part that should closely related to aperture is the pupil.

2) The smaller the aperture, the brighter the picture. The higher the aperture, the darker the picture.

3) If you have a low aperture, the depth of field will also be low because depth of field is how " sharp" objects are. Higher aperture correspondingly means high depth of field.



SHUTTER

High Shutter Speed



Low Shutter Speed



At the beginning while the sun is still partially up and the courtyard has reasonable light

  • a.) the dunking booth - Fast
  • b.) the food eating contest -  Fast
  • c.) the rock climbing wall - Fast 
  • d.) someone working at a booth- Fast
  • e.) the DJ/MC working at the middle of the circle - Fast
  • f.) the Diamonds 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 other.

  • a.) the dunking booth - Medium 
  • b.) the food eating contest - Medium 
  • c.) the rock climbing wall - Slow
  • d.) someone working at a booth - Slow 
  • e.) the DJ/MC working at the middle of the circle - Slow 
  • f.) the Diamonds performance. - Medium


Setting Shutter Speed- Auto Mode means it automatically sets both shutter and aperture 

Shutter Priority Mode means you set the shutter speed and camera automatically sets the aperture.

Manuel Mode means you set shutter and aperture manually 


ISO



ISO 200



ISO 3200



ISO 6400





1) The advantages would be for giving the football game a more brighter setting.

2) The author suggested that you should you low iso when there is plenty of light, so you can retain all the details and have high image quality. 


3) The author suggested that you use a high ISO when there is not enough light so the camera can take the photo quickly.





F4 - the best shutter speed is 1/60 because the background is blurry and the subject is focused its a shallow depth of field

F5.6 - the best shutter speed is 1/60 because the background is for the most part blurry and the subject is focused its a shallow depth of field

F8 - the shutter speed is either 1/30 or 1/60 because for both the backgrounds are blurry and for 1/30 the subject is slightly blurry and for 1/60 its pretty sharp but a little dark.

F11- I would say probably shutter 1/60 is the better shutter speed because the subject is sharp, the background is for the most part is sharp but the photo looks a little under exposed

F16 - the shutter speed that fits most best would be 1/30 because the subject is sharp and the background is also sharp as well. but it might just be slightly under exposed but over all 1/30 is the shutter speed that fits best

F22 - the shutter speed thats best, would be 1/8 because the background is clear and the subjects are some what clear.



when the shutter speed is at its lowest the subjects start to become unfocused. I think the photographer can use a tripod to keep focus.

I think the lowest shutter speed a photographer can hand hold a camera is F16.


I did good on the depth of field quiz, and for the the shutter speed and motion, at first I wasn't do so well but then I stated to get it. I think I understand aperture, shutter speed and ISO a little more. Compare to when I first started I can see an improvement.
