DIGITAL PHOTOGRAPHY AND IMAGING - Week 5
Week 5 (21/MAY/2024)
Lectures:
1. EXPOSURE SETTING
In photography, exposure is the amount of light which reaches your camera sensor or film.
Fig.1.0 Exposure
The main parts of the camera: Camera body, Shutter, Image sensor, LCD screen, Camera lens, Aperture/ Iris.
Fig.1.1 Exposure Triangle
· IRIS: Iris/Aperture is control the flow of light entering the lens.Iris/Aperture is measured by f-stop. (The lower the f-number, the larger the lens opening.)
· SHUTTER: The shutter is a small plastic sheet that opens and closes to allow light onto the film or prevent light from reaching the film.
SHUTTER SPEED: Shutter speed is measured in seconds.

· ISO: Originally referred to the sensitivity of film—it's "light gathering" ability.（The lower the number of ISO the less sensitive your camera is to light and the finer the grain. ）
2. LENS PERSPECTIVE
The are wide angle lens, standard lens and tele lens.
Fig.1.3 Lens Perspective
Lenses can be categorized by FOCAL LENGTH（the shorter the focal length, the wider the angle of view and vice-versa.）.
Fig.1.4 Focal Length
DEPTH OF FIELD: The proportion of the image that is reasonably sharp and in focus.
Fig.1.5 Depth of field
The smaller the aperture you use, the greater the depth of field.
Wide angle lens is especially useful for landscape photography or street photography.(almost everything is in focus)
Standard lens offer a fairly accurate representation of what the human eye sees, both in terms of visual angle and perspective.
Tele lenses are great for isolating a subject that is far away.
3. DSLR V.S SMARTPHONE
Smartphones vs Cameras = Convenience vs Quality
PRO: Familiar with device, Good quality, Easy to learn
CON: Still limited, Good but not great, Non-ergonomic shape
