WEEK 5 : LECTURE

On this week's lecture, Mr Fauzi has introduced us to digital photography.

Week 05 Lecture Note

Lecture Note Week 05

Figure 5.1  Lecture 5

The main parts of a camera are the camera body, lens, sensor, shutter, and aperture. 

Figure 5.2  Main parts of a camera

Exposure Setting
In photography, exposure is the amount of light which reaches the camera sensor or film. 

Figure 5.3  Exposure setting

There are only two camera settings that affect the actual "luminous exposure" of an image: shutter speed and aperture(Iris). The third setting, camera ISO, also affects the brightness of the photos. 

Figure 5.4  3 settings that affect the brightness og the photo

1. Iris/Aperture 

• Controls the flow of light entering the lens.
• Measured by f-stop, indicated by a sequence of f-number: 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....... The lower the f-number, the larger the lens opening, the larger the exposure. 

2. Shtter

• Small plastic sheet that opens and closes to allow light onto the film or prevent light from reaching the film. 

Figure 5.5  Shutter open and close

• Shutter speed
• Snap a lot of frames at one time, must have a tripod.
• Measured in second: 1/1000 s, 1/500 s, 1/250 s, 1/125 s, 1/60 s, 1/30 s, 1/15 s, 1/8 s, 1/4 s, 1/2 s, 1 s, 2 s, 3 s......

Figure 5.6  Example of Shutter speed

Figure 5.7  Example of shutter speed

3. ISO

• Controls the amount of light by the sensitivity of the sensor. 
• Common ISO camera settings are 100, 200, 400, 640, 800, 1600, 3200, 6400......
• The lower the ISO the less sensitive your camera is to light anf the finer the grain 

Lens perspective

There are wide angle lens, standard lens and tele lens. 

Figure 5.8  Example of lens

Appropriate lens provided desire framing, lens choice affects angle of view.

   

Figure 5.9&5.10  Choices of lens that affects the angle of view

1. Focal Length

• Lenses can be categorized by the focal length. 

Figure 5.11  Type of lenses

• The shorter the focal length, the wider the angle of view and vice-versa

Figure 5.12  Focal length

2. Depth of Field 

• The proportion of the image the image that is reasonably sharp and in focus. 
• Refers to how much of your image is in focus

Figure 5.13  Depth of field

3. Lenses (Wide angle lens, Standard lens, Telephoto lens)

• Wide angle lens 
• Ideal for fitting a large area into your frame

Figure 5.14  Use to fit large area into your frame

• Especially useful for lanscape photography or street photography

Figure 5.15  Useful for landscape or street photography

• Standard lens 
• Offers a fairly accurate representation of what the human eye sees, both in term of visual angle and perspective. 

Figure 5.16  Stardard lens

• Telephoto lens
• Great for isolating a subject that is far away.
• Allows to photograph subjects from a distance thanks to the magnification

Figure 5.17  Telephoto lens

Figure 5.18  Allow t o take picture from a far distance

DSLR versus Smartphone 

• Quality: DSLR cameras can take better quality photographs compared to smartphone cameras.
• Sizes: Phone cameras are very limited by size. The size of the lens and the size of the sensor that captures the photos. Entry-level DSLRs have much larger lenses and sensors than mobile phone do.
• Convenience: Smartphone cameras are easier to use compared to DSLR cameras.

WEEK 5 : TUTORIAL

During tutorial session, Mr Fauzi provide us a video to watch.

Video 5.1  How you can make a DIY photography studio at home

In this video, it shared about Tips and Tricks for us DIY Photo Studio.

1. Small objects

• Simply find a consistent backdrop
• Natural curves
• Simple colors
• A piece of paper and use a household lamp as a studio light
• DIY color filter (secure coloures plastic to frame)
• Use baking paper for a DIY Light diffuser

2. Medium objects

• Use roll of paper from stationery store as background 
• Fix to the wall and create a curve 
• Place object near window for natural light 
• DIY reflector (cover a board in kitchen foil)
• DIY flash diffuser (cut an "L" shape from a thin plastic container and fix to camera)

3. Large objects

• Find a plain or consistent wall as a backdrop
• DIY softbox (Cut a hole in the base of a plastic bin, fix lamp with tape, cover with baking paper)

WEEK 5 : PRACTICAL

Project 1B: PART 01 - Digital Imaging Exercise

Part 01: Hearst Mansion

- Follow instructions from the Week_5 Hearst Mansion: https://bit.ly/3CsxWyK
- Follow instructions from the video: https://youtu.be/b6XqlUP-MUA

1.  Digital Imaging Exercise 01 (Part 1: Shazam)

Through this exercise, I learned how to use Quick Selection Tool, Layer Mask, Filters and Color Correcton.

 

Working Progression

2.  Digital Imaging Exercise 01 (Part 2: My Reflection)

Base on Shazam exercise, create the same steps and insert your own photo to replace the Shazam's layer by following these steps: 

1. Take a photo of yourself using the right lighting techniques
2. Apply the Shazam's exercise techniques
3. Replace the Shazam's layer with YOUR OWN PHOTO
4. Apply suitable Colour Correction to finalize your work
