Exercise 2.2 & 2.3 (a) (b)

Lecture

Shutter Speed :

  •  Duration of time that controls how long the light is exposed in the ccd
  • Fast shutter speed "freezes" the object
  • Also measured in second
  • Slow shutter speed normally used to capture movement
When fixing the shutter speed below 1/60" it is recommended for you to use tripod stand to avoid blurry / shaky  image





ISO

  • Sensitive to light
  • Then number of ISO determines the noise of the picture.

INSTRUCTIONS!
Marking Criteria: The student must capture the evidence of the Shutter’s ability to freeze fast moving objects and blur moving objects.

Exercise 2.2 : Shutter Speed

Keep the fan speed at 1 and capture images using shutter settings from 1" of a second till 1/1000th of a second. Repeat the exercise after changing the fan speed from 1 to 2 to 3 and so on.

1/500"             f/2.5        ISO 3200

1/1000             f/2.5              ISO 6400

INSTRUCTIONS !
Marking Criteria: The student must capture the evidence of degradation of image as the ISO increases in sensitivity. The student also must produce evidence that ISO can directly affect exposure.

Exercise 2.3 (a) 
You will be required to shoot a subject using the lowest ISO setting to the highest. Determine the right exposure (shutter speed, aperture at ISO 200) and then increase the ISO setting to 200, 400 and so on.

 ISO 200              1/125                       f.2
 ISO 400            1/125                      f.2
 ISO 800               1/125                      f.2
 ISO 1600               1/125                   f.2
 ISO 3200               1/125                   f.2

ISO 6400                1/125                 f.2

Exercise 2.3 (b)
Determine your exposure (shutter speed and aperture at ISO 200) but this time adjust the shutter speed and aperture to maintain the correct exposure as you increase the ISO.

 ISO 200                  1/100                  f.2


 ISO 400                1/200                     f.2

 ISO 800               1/400                   f.2


 ISO 1600               1/1000                 f.2


 ISO 3200              1/1200                    f.2


ISO 6400               1/4000                  f.2
SCREENSHOTS!




REFLECTION!
  • While Mr. Vinod gave the lecture on how to use the ISO and Shutter Speed, I didn't quite understand. But later after we conducted the exercise, only then I can understand how the Shutter Speed and ISO works. 
  • Basically, the ISO will have relation to the condition of light at the surroundings. 
  • The shutter speed works to freeze or create a moving-like picture. 
FEEDBACKS!
  • Must make sure to have a constant exposure
  • It's Okay if the picture is dark, as long as he can see the image
  • Change my background!!! (done)
  • Be careful with the instructions given
