Exercise 2: Aperture 
Exercise 2a.1: Effect of Aperture on Exposure 
Exercise 2a.2: Depth of Field Controlled by Aperture

 Lecture

Aperture is basically the amount of light that goes through the lens, hitting the sensors.
Which controls exposure and depth of field.

 Instructions
Exercise 2a: Aperture
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).

 Exercise 2a.1: Aperture effect on exposure
Your problem task for the week is to prove the theory as fact that aperture does effect exposure by devising a plan and acting on it.

Exercise 2a.2: Aperture controls Depth of Field
Your problem task for the week is to prove the theory as fact that aperture does effect and control depth of field by devising a plan and acting on it.

Further Instructions:
When updating your ePortfolio ensure you describe your plan before showcasing the evidence that proves the theory. Number your images and include the ISO/F/Shutter Speed settings under every image.
All images must be in black and white. Choose appropriate subject matters for your images.

Feedback

Reflection


Experience -  It's getting a little harder trying to produce these results but it was fun and worth it!

Observation - A lot of buttons and ways to change the settings, at first it was hard but overtime you tend to get used to it.

Findings - Aperture does controls exposure and depth of field!


Feedback - The aperture exercise where you were trying to prove depth of field, while the subject matter and the angle was good, the image got darker as you increased the aperture. This was because you did not compensating adequately for the shutter speed.

07/09/2017 (Week 2) Isyraf Zhong Ren Lim, (300 666 426) Photography Exercise 1: Presentation of 10 of your best-liked pictures Lecture The first class gave me an insight to what we could expect from Mr. Vinod's class. And of course some interesting info on who Mr. Vinod is. I was super impressed and shockd to learn that Mr. Vinod has had some awesome time and work done in the photography industry. Seeing the pictures he had captured and shared to us made me feel as though maybe all of us in class ought to learn a thing or two from our lect! Although it might take a while for me to search for a manual camera and the other equipments, I'm pretty sure I'm able to get one in time before the next class! Instructions • Write your e-portfolio and upload the 10 images along with the description. • Print A4 hardcopy of the 10 selected images with the description following the instructions (margin, font, etc.) given in class and place it in your hardcopy (portfol...

But with the knowledge gained in class with the help of our lecturer Mr. Vinod. He guided not just me but the entire class who weren't a single arts major to fall in love with photography. The technical bits was tough but Mr. Vinod pushed us to work towards his expectations, and tha...
