Introduction to Photography
Exercise 2a.1 & 2a.2: Aperture
Lecture
The class started with Mr Vinod praising a few of us for a job well done on our first e-portfolio assignment (last week). He said some of us made a few mistakes and it was okay to make mistakes as it was our first time doing it but he said to make sure we learn from the mistakes.
He then briefly guide us with more details as to what our e-portfolio posts every week should be like, including how to create the documents on words neatly and also explained to us the differences between observations, findings and experience.
After that, we were all introduced to aperture using the slides. Mr Vinod taught us how aperture affects exposure and depth of field. Mr Vinod even showed us how to change the shutter speed and aperture, also looking through the exposure meter as guide to control the amount of light.
Instructions :
Upon reading, viewing and discussing the material on aperture, we have come to agree that aperture effects exposure (Exercise 2a.1) and controls depth of field (Exercise 2a.2).
Your problem task today is to prove the theory as fact that aperture does effect exposure (Exercise 2a.1) and control depth of field (Exercise 2a.2) by devising a plan and acting on it.
When updating your ePortfolio ensure you describe your plan before showcasing the evidence that proves the theory.
All images must be in black and white, you can make the adjustment in the camera (if the feature is available) or make the adjustment later in an approprite software or Photoshop (directions: Image > Adjust > Black & White)
Do not forget to post the screen shot of the MS word file.
2a) Aperture (5%)
Marking Criteria: 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.
Learning goal: Students are able to prove that aperture effects exposure and depth of field.
Learning outcome 1: Students will be able to use exposure settings (Aperture).
Learning outcome 3: Students will be able to distinguish a bad exposure from a good exposure.
Instructions for Exercise 2a.1
1. Take a picture of any image starting with the right exposure combination of shutter speed and aperture (maintain ISO at 200).
2. Start your aperture setting from the lowest f-stop (f1.4/f2.0/f3.5) to the highest f-stop (f16, f22).
3. Do not change the shutter settings as the aperture is increased.

Instructions for Exercise 2a.2
1. Take a picture of any subject, focusing on the foreground with the right exposure, combination of aperture and shutter speed (maintain ISO at 200)
2. Start your aperture setting from the lowest f-stop (2 / 2.8 / 5.6) to the highest f-stop (16 / 22 / 32)
3. Change the shutter speed as aperture is increased
2a.2 Prove that aperture controls the depth of field
(6)
F5.6 S1/500 ISO200

(11)
F32 S1/20 ISO200

Feedback
Farah, well done! You managed to prove that aperture effects exposure and controls depth of field through the evidence showcased on your blog. It was clear and concise, good job.
The instructions for your eporfolio was incorrect, please use only what has been posted on Facebook. I have realized that in my instructions posted I had not included the marking criteria (although it's available on the yourbrief blog) and the learning goal, as such I have amended the post to include the said. So please delete the instructions on your blog that comes via the slides and copy paste the amended version from FB.
The reflection of your findings was also good, it was quite detailed and that is promising. I like that you explained the observations and findings from your exercise, good job. Please continue to get better and ensure you read the definition every time you write the reflection.
Reflections
Experience :
Today was the first time I used the dslr using the manual mode. It felt difficult at first because when I changed it to manual, the picture I photographed looks really dark when I tried capturing.
When we were told to take our pictures outside the class, everyone scattered to find good spots to capture, so I tried to do both 2a.1 and 2a.2 assignments and was really amazed with the pictures that I captured. It felt good getting a picture the way we want it to be photographed. I find that I have to really try things to understand how it works, and thats how I slowly learn to understand how aperture and shutter speed work to provide the correct amount of light entering the lens and the clarity of the background.
Like Mr Vinod said, each of us only get a little bits of pieces of what he said during class so when we had trouble photographing the pictures, we asked for each other's help.
Now i understand how to use aperture and shutter speed properly when using manual mode.

Observations :
Mr Vinod explained really well and I understood how aperture works altogether with how to adjust the shutter speed to get the photograph to be the way we wanted. I noticed how good it feels seeing the picture we took came out as expected, just the way we want it to be.
I also noticed that I did not know how to make the camera focus and do the assignment 2a.2 properly, so I got Hazel's, Lana's, Sarah's and Jo's help. (Thanks guys!!)

Findings :
Now I know how to adjust the aperture and also the shutter speed in order to get the right amount of light to enter the lens, hence creating a photograph the way we want it to be.
I found that I can be out of focus sometimes in class so I need to fix that by listening to Mr Vinod attentively while jotting down points in my notebook.
I realised that the number of the lowest aperture differs when we zoom in (largest mm) and zoom out (lowest mm). Also, I learned that the smaller number of aperture allows more light to enter the lens and vice versa. Other than that, I learned that when the exposure was the lowest, the picture is dark when captured. So, to fix that, we'd have to lowered down the shutter speed. Next, in order to control the depth of field in the camera, I should lower the number of aperture (while adjusting the shutter speed to apply the right exposure) so that I get a blur background and vice versa.
