Aperture, Shutter Speed, ISO - how do they all work?

aperture

aperture



fast shutter speed

  • The eyes puple  are the the are closely related to aperture 
  • the smaller the Aperture the bigger the f number is the higher the Aperture the smaller the f number is  
  • aperture impacts the focus of a photo   
  • f 4.0 ,f 4.5 , f 5 ,f 5.6 ,f 6.3 , f 7.1 ,f 8.0, f 9.0 ,f 10 , f 11 , f 12 ,f 13 ,f 14 , f 15 f 16, f 18, f 20 ,f  22, f 25                                    SHUTTER SPEED   
  • slow  shutter speed
a).a dunking booth: high shutter
b).eating food contest : high shutter 
c). rock climbing  wall :  high shutter 
d). some one working at a booth : high shutter 
e.) the DJ/MC working at the middle of the circle: high shutter
f.) the Diamonds performance: high shutter 


                                                           DARK
a.) the dunking booth: low shutter
b.) the food eating contest: low shutter
c.) the rock climbing wall: low shutter d.) someone working at a booth: low shutter
e.) the DJ/MC working at the middle of the circle: low shutter
f.) the Diamonds performance: low shutter
  •  Aperture priority -is when you manually set the lens  
  • shutter priority- is when a mode were you set the shutter and the camera sets aperture 
  • manual - is when were you set shutter speed and aperture manually

  1. the advantages of shooting in ISO like at a sporting event is taking the pictures in high quality
  2. the suggestions the author said were to use low ISO when good lighting.
  3. the suggestions the author said to use high ISO when there isn't good lighting



                                                    SIM CAMERA    
  • F 2.8 1/125
  • F 4  1/ 125  
  • F 5.6 - 1/60
  • F 8 1/60 
  • F 11 1/60
  • F 16 1/30 
  • F 22 1/8
  • at f  4 background is still blurry 
  • at f 5.6 background is blurry but you can start to tell what it is 
  • at f  8 background  getting clearer 
  • at f 11 background is clear but not compleatly crisp
  • at f 16background is same  as f 11 
  • at f  22 background is very crisp
