Aperture, shutter speed, ISO

   

  F2.8

 

F16 

1. We closely relate aperture to the human eye.

 

2. The smaller the Aperture The littler the focus, more blur , the higher the Aperture the bigger the     

    focus,and more sharp.

3.Aperture controls the Depth of Field by making the background look blurry or sharp

High shutter Speed

 

Low shutter speed.

1.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...MEDIUM
• c.) the rock climbing wall....MEDIUM
• d.) someone working at a booth.....SLOW
• e.) the DJ/MC working at the middle of the circle...SLOW
• 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...MEDIUM
• d.) someone working at a booth...SLOW
• e.) the DJ/MC working at the middle of the circle..SLOW
• f.) the Diamonds performance....MEDIUM

 2.Aperture priority- you control the aperture and the shutter sets to fit with your aperture.

    Shutter priority- you control the shutter speed.

    Manual- everything is set and adjust for you.

ISO 200

ISO 6400

1. What are the advantages of shooting with a higher ISO setting at a sporting event like a night football game? The more light it captures.

 

2. What suggestions did the author make about using a low ISO? For most places with good lighting stick with the low only rare cases would you use a low ISO in a dark or dim area

 

3. What suggestions did the author make about using a high ISO?

when their isn't enough light you should always use a high ISO.

• F4  ...1/125, blurry,
• F5.6  ...1/60, more blurry,
• F8 ....1/60 ,......less blurry
• F11 ....1/60...less focused
• F16 ....1/30 .....more focused
• F22.....1/30.... focused

Finally, what is happening to the subject (the people) at SLOW Shutter Speeds? What could the photographer do to help combat this problem? At slow shutter speeds the couple is blurry, to fix this a photographer should change the iso.

What is the lowest Shutter Speed do you think a photographer can hand-hold the camera without a tripod? 1/125
