Digital Photography

Exposure Setting

Exposure

• Exposure in photography is the light that reaches your camera sensor or film.

Fig 1.0 Exposure setting 

Main parts of the camera :

1. Camera body :

The camera body is a light proof box.

• Shutter
• Image sensor
• LCD screen

2. Camera lens :

• Aperture/ Iris

Fig 1.1 Parts of camera

Only two camera settings affect the image's exposure: shutter speed and aperture. The third setting, ISO, also impacts photo brightness.

IRIS : The iris/aperture controls light flow into the lens.

The iris/aperture is measured by f-stop, indicated by a sequence of f-numbers (e.g., f/1, f/1.4, f/2, etc.). A lower f-number corresponds to a larger lens opening.

Fig 1.3 Lens opening Ex.2

Shutter : 

• The shutter is a sheet that controls light access to the film.
  
  
• Shutter Speed : Shutter speed is measured in fractions of a second: 1/1000s, 1/500s, 1/250s, 1/125s, 1/60s, 1/30s, 1/15s, 1/8s, 1/4s, 1/2s, 1s, 2s, 3s, etc.

Shutter Speed Example :

ISO : 

• ISO is a camera setting that determines the sensitivity to light, ISO refers to the sensitivity of film or the camera's sensor in digital photography. Common ISO values include 100, 200, 400, 640, 800, 1600, 3200, 6400. Lower ISO numbers result in less sensitivity to light and finer grain.

Lens Perspective

Different types of lenses, such as wide-angle, standard, and telephoto, offer varied angles of view and framing options. Lens choice depends on the desired composition, and lenses can be categorized based on their focal length.

Fig 1.8 Types of Lenses

Focal Length : 

• Focal length determines the angle of view of a camera lens. Shorter focal lengths result in wider angles of view, while longer focal lengths provide narrower angles. It is measured in millimeters from the lens's optical center to the camera's sensor.

Fig 1.9 Focal Length

Depth of Field : 

• Depth of field refers to the portion of an image that appears sharp and in focus. It is influenced by the aperture setting, with smaller apertures resulting in greater depth of field.

Type of  Lenses 

1. Wide-angle Lens :

• Wide-angle lenses are great for capturing expansive scenes and fitting a large area into the frame. They are particularly well-suited for landscape and street photography. With wide-angle lenses, most elements in the frame are in focus, except when the subject is very close to the lens.

2. Standard Lens : 

• Standard lenses provide a close approximation to the visual angle and perspective of the human eye. They offer a natural and accurate representation of scenes, making images appear more realistic compared to other lens types.

Fig 1.11 Standard Lenses

3.Tele Lens :

• Telephoto lenses excel at capturing distant subjects by providing magnification and allowing you to isolate them effectively. They are ideal for shooting from a distance and enable you to photograph subjects that are far away.

Fig 1.13 DSLR Vs Smartphone

Pros and cons of smartphones : 

Pros 

• Familiar with device
• Good quality
• Easy to learn

Cons

• Still limited
• Good but not great
• Non-ergonomic shape

Smartphones vs Cameras = Convenience vs Quality

• Smartphones prioritize convenience and multifunctionality, while DSLR cameras prioritize image quality and specialized photography. Phone cameras are limited in size, including the lens and sensor, compared to entry-level DSLR cameras that have larger lenses and sensors.

Practical : PHOTO MANIPULATION

PART 1: Hearst Mansion : Shazam

Following the instruction Mr.Fauzi gave us i start cutting the picture of Shazam on photoshop using the quick selection tool.

Fig 2.0 Cutting progress of Shazam.

After cutting Shazam i started positioning into the position that i like and where it feels natural. 

Fig 2.1 Placing Shazam into the Mansion

And then i start with color adjustment to make sure it looks like he blend into the mansion.

Fig 2.2 Color adjustment

I proceed with adding shadows in the back to make it more natural and blending into the background 

Fig 2.3 Adding Shadows

I proceed to add reflections to make it more real and manipulate the image even further , by reflecting the shazam image and added some filters such as gaussian blur and changing the hues.

Fig 2.4 Adding reflection

Final Result 

Fig 2.5 Final Result

After doing all the steps i feel satisfied with the result , he seems to be blending into the environment. i tried to make him smaller but i feel like its proportionally wrong, the result doesnt look bad to me so i trusted my judgement and decided this will be the final result.

PART 2 : Hearst Mansion : Me !

Mr.Fauzi told us to do the same thing but this time using our own picture so i used the picture when i was doing cosplay!

Fig 3.0 Cutting progress of Me

After cutting i process to place myself and then add some color adjustment

Fig 3.1 Placing Me into the Mansion and Color adjustment

and then i added some shadows to blend more into the picture

Fig 3.1 Adding Shadows

then lastly i proceed to add reflection and adjust it to blend into the water!

Fig 3.3 Adding reflection

Final Result 

Fig 3.4 Final Result

it was very fun to do this assignment and it could be a really silly thing to do to edit stuff into a background. 

Reflection

• Very fun assignment once again because ive always wanted to learn photo manipulation on photoshop! a great opportunity to learn hopefully i can apply what i learn into my photo editing hobbies in the future.
