From this lecture slide, I understood...
Exposure Setting
- Exposure in photography is related to the amount of light that reaches the camera's sensor or film. Exposure is a fundamental concept in photography, as it directly impacts the quality and outcome of the photograph. Exposure is a crucial element for controlling the brightness, darkness, and overall look of a photograph. Exposure can be adjusted by various settings on a camera, such as aperture, shutter speed, and ISO, to control the amount of light hitting the sensor or film.
fig 1.1. Underexposed Vs Correctly Used Vs Overexposed
- The main parts of the camera:
* Camera Body
* Shutter
* Image Sensor
* LCD Screen
* Camera Lens
* Aperture / Iris
The camera body is a light-proof box

2. Shutter Speed
3. ISO
- Shutter speed and aperture are the two settings that directly impact the "luminous exposure" of an image. These settings have a significant effect on how much light enters the camera and, consequently, the overall exposure of the photograph. The third setting, camera ISO, also influences the brightness of photos. However, it may not directly affect the "luminous exposure" as shutter speed and aperture do.

*IRIS*
~ Is to control the flow of light entering the lens

~ The lower the f-numbers, the larger the lens opening.

*Shutter*
~A small plastic sheet. The function of the shutter is to open and close. The purpose of opening and closing the shutter is to control the amount of light that reaches the film.
4. The shutter can either allow light to pass through onto the film (when it's open) or block light from reaching the film (when it's closed).
~ It is a crucial component in controlling exposure and capturing images on photographic film or digital sensors.

*ISO*
~ Originally referred to the sensitivity of the film, specifically its "light gathering" ability. In the context of digital photography, ISO refers to the sensitivity or signal gain of the camera's sensor. This information is related to the technical aspects of photography and how ISO settings affect the exposure of a photograph.
fig 1.6. The Value Of Using Higher ISOs
~ The common ISO camera settings are --- 100, 200, 400, 640, 800, 1600, 3200, 6400.
~A lower ISO value on your camera, means if you are using a lower sensitivity setting. Lower ISO values are typically used in well-lit conditions. Lower ISO values make the camera less sensitive to incoming light. In bright environments, using a lower ISO setting helps prevent overexposure. When you use a lower ISO setting, the resulting image will have less visible grain or noise. Lower ISO values produce smoother and cleaner images, especially in situations with ample lighting.

Lens Perspective
- There are 3 types of camera lenses which are: Wide-angle lenses, Standard Lenses and Telephoto Lenses
- Wide-angle lenses capture a wider field of view.
- Standard Lenses are typically used for general photography
- Telephoto Lenses are used for zooming in on distant subjects.
*Focal Length*
- There are various types of lenses, each created with a specific use or application in mind. Lenses are not one-size-fits-all but are tailored to fulfil various functions. One way to classify or categorize lenses is based on their focal length. Focal length is a critical characteristic of a lens and determines its field of view and other optical properties.
- The shorter the focal length, the wider the angle of view and vice-versa.
fig 1.8. Types Of Camera Lenses
*Depth Of Field*
- 'Proportion' suggests that not the entire image is necessarily sharp or in focus, but only a certain part or percentage of it. The image quality may not be perfect, but it meets an acceptable standard of sharpness and focus, implying that some parts of the image might be less clear or out of focus.
fig 1.9. Depth Of Fields
- The smaller the aperture you use, the greater the depth of the field.
DSLR vs Smartphone
- DSLR cameras are designed with the primary purpose of capturing images, indicating that their main function is photography.
- Phones, on the other hand, are designed for a wide range of functions or activities beyond just capturing images. They are versatile devices capable of performing various tasks, such as making calls, browsing the internet, sending messages, running applications, and more.

DIGITAL IMAGING EXERCISE 1 (5%)
- Photo Manipulation (Hearst Mansion)
Submission: WEEK 6
Today we were to edit out Shazam's figure and attach it to a picture called Hearst Mansion. Both pictures were provided by Mr Fauzi. After that, we were asked to take our own picture instead and edit it out. We were asked to watch a tutorial video to assist us while we were doing our work. After watching the video, I immediately began my work.
This is my final work with Shazam's figure edited out.

After this, I then started to take an eye-level picture of myself.
fig 1.1. Eye-level Picture Of Myself
Since I didn't have someone to help me out, I used a phone stand and chairs to help me and I made sure that it was at eye level as this is a requirement. Then I began to edit myself.

I played around with the adjustment and filters to my liking and after Im done, I started to do the reflection in the waters

Reflection
I dived into the captivating world of lens perspective. This week's focus on the impact of different lenses on the composition and storytelling in photography was eye-opening and enriching.
One of the key takeaways from this week was the realization that the choice of lens is not merely a technical decision but a creative one. Different lenses, whether wide-angle, standard, or telephoto, offer unique perspectives and possibilities for storytelling. This week's lessons underscored the significance of selecting the right lens to convey the desired message and create engaging visual narratives.
The wide-angle lens, for instance, offers a broad field of view and is perfect for capturing expansive landscapes or adding a sense of grandeur to architectural shots. In contrast, the telephoto lens allows for tight framing and is ideal for isolating subjects from their surroundings, emphasizing details, and bringing distant scenes closer. The standard lens provides a natural perspective, making it suitable for a wide range of subjects.
