Digital Photography & Imaging - Week 5

-
Lecture
Our lecture for this week introduced us to digital photography and the main functions on a camera, those being:


Exposure:
- The amount of light that reaches the camera sensor or film.
- Underexposure: Not enough light is captured / Too dark
 - Correctly Exposed: The perfect balance of light and dark
 - Overexposed: Not enough darkness is captured / Too bright


Iris/Aperture:
- The control over the flow of light that enters the lens
- Measured by an F-Stop, indicated by a sequence of F-Numbers: f/1, f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22, f/32 and so on. The lower the lens number, the larger the lens opening


Shutter:
- A small plastic sheet that opens and closes to allow light onto the film or prevent light from reaching the film.
- Shutter Speed is measured in seconds: 1/1000s, 1/500s, 1/250s, 1/60s, 1/30s, 1/15s, 1/8s, 1/4s, 1/2s, 1s, 2s, 3s, and so on. The smaller the shutter speed, the more clearer something becomes.


ISO:

- Originally referred to the sensitivity of film, its "light gathering" ability. For digital photography, ISO refers to the sensitivity---the signal gain---of the camera's sensor.

- The common ISO camera settings are: 100, 200, 400, 640, 800, 1600, 3200, 6400, and so on.

- The lower the number of ISO the less sensitive your camera is to light and the finer the grain.



Tutorial
For our tutorial we were introduced to tips and tricks that we can use to perform a studio style shoot at home using DIY tips.


Practical
Our practical work for this week was to work on our Hearst Mansion project which is split into two sections, the first part has us cut out Zachery Levi's character of Shazam from a poster and place him into a photo of the interior of the Hearst Mansion before editing his outline to create a believable appearance. The second part has us edit ourselves into the Hearst Mansion using the same techniques that we used for the first part.

Exercise 1: Hearst Mansion Shazam Edit


Exercise 2: Hearst Mansion Personal Edit

We then have to present it in a layout or graph visually. Figure 1.1: Raw Data For the objects that I would use for this exercise, I decided to go with Lego Technic pieces since I have an entire drawer filled with them so it would be interesting to see what I could do with them. I went with three different pieces since I had a high quantity of them compared to other the other pieces in my storage. Figure 1.2: Data Sorted I sorted the data into three simple categories, which was colour. Figure 1.3: Data Arranged I then arranged them neatly in their respective categories and added in the names for the specific piece that I used.  Figure 1.4: Data Pres...

Figure 1: Dissertation Draft Task 2: Visual Design For the second task of this module, we had to create a visual design for our dissertation by turning it into a flipbook styled paper, on top of that the visual design and aesthetic has to match and share a similar theme with the dissertation's topic. Because my dissertation is on indigenous cultures and representation, I decided to try and create a design using elements that they would have used in the past to create books. I used buckskin as the cover and parchment for the pages so that it wou...

Game Art - Final Project: Art Bible

11.12.2024 - 10.01.2025 / Week 12 - Week 15 Ilhan Rayan bin Khairul Anwar / 0361205 Game Art / Bachelor of Design (Honours) in Creative Media Final Project - Art Bible INSTRUCTIONS PRACTICAL With the work completed to a level that I'm satisfied with, I started uploading everything together onto one shared slideshow as my Art Bible. Because this module is connected with Environment Design, I included the drawings that I had made in that module in the slides since they were also Marvel Rivals based. Because my classmate told me that we needed cover art for our art bible, I decided to repurpose my unused splash art that I made for the cover since I did not have enough time to design an entirely new cover just for the art bible. REFLECTION I found this module overall to be the most fun of the three that I took this semester. I really enjoy this sort of work where I get to come up with concepts for a character which is the kind of work that I'm interested in. I enjoy coming up with ...
