WEEK 11: LECTURE

Figure 1.1: Week 11's lecture session

Figure 1.2: Week 11's tutorial session

    In this week's class session, we were all given a quick briefing about our final project. Mr. Fauzi also gave us some guidelines to complete this final project. In the tutorial session, Mr. Fauzi gave a more detailed explanation of problems that we had when completing the animation in week 10's tutorial. In the practical session, we were taught by Mr. Martin and he taught us how to use different lighting positions to take portrait photos. All the photoshoot outcomes were documented in the section down below.

Figure 1.4: Demonstration of exposure in photography

    Exposure in photography is very important because it allows the brightness of the overall photo to be correctly exposed. It is defined as the amount of light that reached the camera sensor or film. 

Figure 1.5: Breakdown of camera body and lens

    To create a well-balanced picture that is also well-exposed, we need to understand the balance of the 3 basic manual camera settings. They are the aperture, shutter speed, and ISO.

Figure 1.7: Overview of different aperture size

    When adjusting the aperture size, the larger the opening is determined by the lower value of f (f-stop). 

Figure 1.8: Overview of shutter speed

    The shutter as shown above is played around by changing the shutter speed. Shutter speed is determined by the speed of when the shutter opens and closes to allow the subject to be captured by the camera sensor. The higher the shutter speed, the lesser light will be captured. However, the picture will be clearer and sharper because movements by the subjects would not be captured.

Figure 1.9: Overview of ISO setting

    ISO is originally referred to as the sensitivity of film. It is the ability to increase or decrease the brightness of the picture taken. However, the higher the ISO, the more grain we would see in the picture taken. 

Figure 1.10: Overview of different lenses

    To adjust the zooming in and out of a photo, we would use different types of lenses because they each have a different focal length range, or some have a limited focal length range. Prime lenses are the ones with fixed focal length and therefore, we would not be able to zoom in or out when taking a picture. THe lower the value of focal length, the wider the shot would be.

Figure 1.15: Comparison between DSLR camera and smartphone

    It is better to use a camera (either mirrorless or DSLR) because it is designed to capture images. Phones, on the other hand, are designed to carry out a multitude of functions. Phone cameras are also very limited by size. The size of the lens is the size of the sensor that captures the photos. THe larger sensor size on a camera makes it better when compared to smartphones.
