LECTURES
Week 5:
Exposure
Exposure is the amount of light which reaches the camera sensor or film.
Fig 1.5.1 Different exposure of photo
Parts of Camera
The main parts of the camera:
Camera body:
- ShutterImage
- SensorLCD screen
Camera lens:
- Aperture/ Iris
Fig 1.5.2 Structure of Camera
Exposure Setting
Camera settings that affect the luminous exposure:
- Shutter speed: The speed at which the camera shutter is closed that allow the light to reach the film.
Fig 1.5.3 Different Shutter Speed
- Iris / Aperture: Control the flow of light entering the lens.
- ISO: Camera's sensitivity to light. The lower the number of ISO
Fig 1.5.4 Different ISOs
The lower the number of ISO, the less sensitive the camera to light and the finer the grain.
Fig 1.5.5 Relationship between Shutter Speed, Iris and ISO
Lens Perspective
Appropriate lens provided desire framing, lens choice affects angle of view. Lenses can be categorized by focal length.
Fig 1.5.6 Types of Camera Lenses
Focal Length
The shorter the focal length, the wider the angle of view and vice-versa. Focal length is the measurement from the optical center of a camera lens to the camera’s sensor.
Fig 1.5.7 Focal Length
Depth of Field
The proportion of the image that is reasonably sharp and in focus. The smaller the aperture you use, the greater the depth of field.

Week 6:
The principle of deisgn are the rules to create effective and attractive compositon. These are some fundamental principles of design:
- Emphasis
- Balance
- Alignment
- Contrast
- Repetition
- Proportion
- Movement
- White space
Week 5:
Hue is a degree on the colour wheel from 0 to 360. 0 is red, 120 is green, and 240 is blue. Saturation is a percentage value. 0% means a shade of gray, and 100% is the full color.
Mr Fytullah suggested us to display the design work in different screens to ensure the colours are ideal.
Mr Fytullah gave the example, if we brighten the poster of "Grave Of The Fireflies"(1988), we will notice that some of the lights are not fireflies, but incendiary bombs from a B-25 bomber. This is a great example in playing with the levels of colour.
While adjusting the Curves adjustment layer, the white balance will be affected.
Mr Fytullah gave us some tutorial in using Colour Balance (Ctrl+B), Hue / Saturation adjustment (Ctrl U), Levels (Ctrl+L)
Week 6:
We were given brief tutorial by Mr Fytullah regarding the using of quick selection tool, filter, layer mask and colour correction before starting the practical exercise. These are the basic tools used for matching a character into an environment. We were instructed to do recolouring of exercise. Different blend modes such as Screen, Overlay and Soft Light are used in this exercise.
Week 6:
In this week, we are instructed to do a digital imaging exercise, which is matching the character Shazam into a hearst mansion.
These are a few technics we are instructed to practise:
- Quick selection tool
- Layer mask:
- Filters
- Colour correction
Quick seelction tool and layer mask are used to substrate background character.

After resizing the character, I try to match the character into the background. Colour Balance, Match Colour and Curves Adjustment layer are used to adjust the colour. I added some shadow with Gaussian Blur filter, noise filter was added to the character too.
I added a Soft Light layer to the character because of the yellow light in the left.
Fig 3.6.3 Shazam matched with the environment
For the reflection, I copy the image, lower down the opcacity and added a multiply layer to further darken the reflection in the bottom side. Saturation of the reflection was lowered down. Ripper filter was added to imitate water reflection.

Fig 3.6.5 Shazam & Hearst Mansion
Now, we were instructed to match our own picture into the hearst mansion.

After applying the same step, here is my outcome:

Week 7:
In this week, we are instructed to recolour a black and white image. Quick Selection Tool, Marquee Tool, Brush Tool, Refine Edge Brush Tool and layer Mask are used in this exercise. For the Blending Mode, Softlight and Overlay are mostly used.
These are the black & white image given.

REFLECTION
In this project, I have developed my understanding in the use of blending mode. I learned how applying gradients can transform an image dramatically. Gradients allow for a natural transition between different tones, which bring a sense of unity to the image. I found that this technique is particularly useful when trying to harmonize different elements make that the overall colours feel cohesive. Besides, I have more understanding in layer's blending modes, especially Multiply, Screen, Overlay and Soft Light. Different modes do give different results. Lastly, I learned how to readjusting clippping mask by using refine edge tools. This enhance my accuracy while recolour the photo.
