Aperture

18.4.2014, Week 3

Introduction to Photography
"Aperture"

Lecture:
Last week, Mr. Vinod told us to do a research about aperture. Today, we were all asked to form a circle at the center of the room while facing each other and start a discussion about aperture. We questions and answers it with what we know. Some of the question doesn’t even have an answer to it. For example, “Do our phone camera had aperture too?” After the group discussion ended, Mr. Vinod give us a briefing about aperture, more details and explanation. He also gave an answer for some of those unanswered question. After that, Mr. Vinod asked us to carry out an exercise in order to understand it more and prove it with the theory he told us was right. According to him, it’s important to remember the F numbers, especially the main number {2, 2.8, 4, 5.6, 8, 11, 16}

Objectives:
  • Does Aperture controls the exposure?
  • Does Aperture controls depth of field?

Instructions:
1. Use a subject that is repetitive in nature.
2. Keep your zoom lens fixed at 35mm and ISO at 200.
3. Do not move your camera position at all when taking shots in different settings.
4. Record the ISO, shutter speed and F-number used in the picture captured.

Instructions for Exercise 2a.1:
  1. Take a picture of your repetitive subject starting with the right exposure combination of shutter speed and aperture. 
  2. Start your aperture setting from the lowest number (f1.4/f2.0/f3.5)
  3. Do not change the shutter settings as the aperture is increased.
Instructions for Exercise 2a.2:
  1. Take a picture of your repetitive subject starting with the right exposure combination of shutter speed and aperture. 
  2. Start your aperture setting from the lowest number (f1.4/f2.0/f3.5)
  3. Compensate the increase of your aperture with your shutter settings as the aperture is increased to maintain the right exposure.
Marking Criteria:
Exercise 2 : Aperture (5%)The student must capture the evidence of the Aperture’s influence in exposure using the various f-stops. The student must also capture the evidence of the Aperture’s influence on depth of field.

ISO : 200
Aperture : F16
Shutter Speed : 1/100
ISO : 200
Aperture : F22
Shutter Speed : 1/100
ISO : 200

Exercise 2.a.2:
Determine if Aperture controls depth of field

 Aperture : F5.6
Shutter Speed : 50
ISO : 200
 Aperture : F8
Shutter Speed : 25
ISO : 200
 Aperture : F11
Shutter Speed : 13
ISO : 200
 Aperture : F16
Shutter Speed : 6
ISO : 200
Aperture : F22
Shutter Speed : 4
ISO : 200

Feedback :
Specific feedback:
Mr. Vinod told me I did a good work with regard to the exercise. He also said that the results seems accurate and reflect the requirement of the criteria. He said that ePortfolio was well written and told me to keep on improving it. Mr. Vinod said that I should express myself freely (negative or positive) with regard to the lesson, activities and describe them in my reflection. 

General feedback:
Mr. Vinod told us that we did well on our eportfolio  

Reflection:
Experience:
From today class, I realize that we are able to exchange knowledge better from doing the group discussion. Since it was the first time we are actually this kind of discussion, most of us just stay silent and only a few speaks. But slowly we were able to engage into the conservation. Some of the questions are difficult to give an answer, not only us but also Mr. Vinod. It was actually quite fun doing this as we are more relaxed around our classmates. 

Observation:
I realize that I understand aperture more hands-on rather than reading about it. Not like I’m saying reading is useless, it’s part of our general knowledge in photography. It’s better to understand it more before handling the camera first. During the group discussion, I realize that all those exchanged information about aperture was very useful. Even I didn’t even think about that. It was very refreshing, about how the ideas I never heard about flows through the discussion or when I wasn’t able to understand it even though I did my research. I was so confuse to use my camera in manual mode for the first time but some of my friends helped me with that and I was able to do finished the exercise.

Findings:
At today class, I notice that everyone begin to become an active learner and so do I. When I was doing the exercise outside, I also notice that everyone was helping with those who had problems with their camera. As for my tripod, I was having problem with it since I’d never used it before and some of the senior helped me with it. I would need to practice more about handling the camera with manual mode since Mr. Vinod told us that he won’t always help us.
