Aperture, Shutter Speed, & ISO

Aperture

Photo taken at aperture level F16

1. We should closely relate aperture to the eye.
2. The smaller the Aperture size, the higher the Aperture number.
3. Aperture impacts Depth of Field because when the aperture number is smaller the foreground is sharper/more in focus than the background. As the aperture number increases/gets bigger the background begins the become more visible and less blurred out.

Shutter Speed:

1. If you were assigned to shoot at Bulldogs and Hotdogs night, what shutter speeds do you think you would have to shoot at the following events that night?

At the beginning while the sun was still up the courtyard had reasonable good light:

         a) a booth in the middle of the yard near the Tree - low shutter speed

         b) a food booth outside under one of the big red awnings - low shutter speed

         c) the Stars performance inside the gym - high shutter speed

         d) students dancing near the center of the courtyard - high shutter speed

         e) people streaming in from the front doors - low shutter speed

         f) the basketball booth where students are shooting basketballs at a hoop - high shutter speed

    

Towards the end when there is no sun and has gotten dark enough that you can't see from one            end of the courtyard to the other.

        a) a booth in the middle of the yard near the Tree - low shutter speed

         b) a food booth outside under one of the big red awnings - low shutter speed

         c) the Stars performance inside the gym - high shutter speed

         d) students dancing near the center of the courtyard - low shutter speed with flash

         e) people streaming in from the front doors - low shutter speed with flash

         f) the basketball booth where students are shooting basketballs at a hoop - high shutter speed

2. The three settings on your camera regarding setting shutter speed are Aperture Priority, Shutter Priority, and Manual. In aperture priority, the photographer manually sets the aperture and the shutter speed is automatically set. In shutter priority, it is the opposite where the photographer sets the shutter speed and the camera automatically sets the aperture. In manual, the photographer will have to manually set both the shutter speed and the aperture without the camera setting them automatically.

ISO:

1. The advantages of a shoot at a higher ISO at a sporting event like basketball or a night football game consist of the motion being frozen in time so that the images don't appear blurry.

2. The suggestions the author made about using a low ISO were to stick to the base ISO as much as possible, and use it for some dark environments.

3. The authors suggestions about using a high ISO were you should increase it when there is not enough light available, you can use it to freeze motion, if you want yo get ultra-fast shots.
