Exercise 2c: ISO
2c.1) ISO effects exposure
2c.2) ISO effects image quality
Exercise 2b: Shutter Speed

Lecture
ISO affects the light of the picture, the lower the ISO the clearer the photo will be produced and the higher the ISO, the noisier the picture will be. Shutter speed could be used to snap clear pictures of fast moving objects.

 Instructions
Exercise 2c: ISO
2c.1) ISO effects exposure
2c.2) ISO effects image quality
Upon reading, viewing and discussing the material on ISO, we have come to agree that ISO effects exposure (Exercise 2c.1) and effects the quality of an image (Exercise 2c.2).
Your in-class task today, requires you to prove that:

 2c.1) ISO effects exposure
2c.2) ISO effects the quality of an image by increasing the noise and grain of a picture.

 Exercise 2b: Shutter Speed

 We have already proven that shutter speed effects exposure (2a & 2c). Your task is to now prove that shutter speed has the ability to freeze fast moving objects and blur moving objects.

 All images must be in black and white, using sun light. Ensure you are shooting at the highest quality JPEG.

 Exercise 2c.1) ISO effects exposure
Exposure time: 1/500 sec. 
F-stop: f/8
ISO: 100
Device: Canon EOS 1300D

Exposure time: 1/500 sec. 
F-stop: f/8

ISO: 200

Device: Canon EOS 1300D


Exposure time: 1/500 sec. 
F-stop: f/8
ISO: 400
Device: Canon EOS 1300D

Exposure time: 1/500 sec. 
F-stop: f/8
ISO: 800
Device: Canon EOS 1300D




Exercise 2b: Shutter Speed

Exposure time: 1 sec
F-stop: f/8
ISO: 200
Device: Canon EOS 1300D
Exposure time: 1/4000 sec. 
F-stop: f/8

ISO: 200
Device: Canon EOS 1300D


Reflection
Experience - This is a lot tougher than the aperture assignment, but I had help from fellow classmates which were really nice.
Observation - I find myself moving the camera while snapping the pictures even with a tripod, it really knows how to test ones patience!

Findings - Shutter speed , aperture and ISO, those three main set controls the picture quality.

Feedback - You did not showcase the ISOs ability to effect quality of image. While you were successful in showing the shutter speed is able to freeze moving objects you did not compensate the aperture of ISO when increasing the shutter speed as such the image turned out darker.

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...
