LECTURE

Digital Photography

Exposure Setting

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

Fig 1.0: Exposure (7/11/2021)

Main parts of the camera

1. Camera body:

- Shutter

- Image sensor

- LCD screen

2. Camera lens

- Aperture / Iris

Camera body is a light proof box. 

1. IRIS

2. SHUTTER SPEED

3. ISO

- only two camera settings that affect the actual "luminous exposure" of an image: shutter speed and aperture 

- third setting, camera ISO, affects the brightness of your photos

IRIS

- control the flow of light entering the lens

- measured by f-stop, indicated by sequence of f-number

- the lower the number, the larger the lens opening (more light that comes in)

SHUTTER

- 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 is measured in seconds

ISO

- originally referred to the sensitivity of film - light gathering ability

- refers to sensitivity - the signal gain - of the camera's sensor

- common ISO settings are 100, 200, 400, 640, 800, 1600, 3200

- the lower the number of ISO the less sensitive your camera is to light and the finer the grain

Lens Perspective

- wide angle lens, standard lens and tele lens

- different lenses are designed for different purposes

- can be categorized by focal length

Fig 1.4: Types of Camera Lenses (8/11/2021)

Focal Length: The shorter the focal length, the wider the angle of view and vice-versa.

- measurement (in mm) from the optical center of a camera lens to the camera sensor

Depth of Field

- the proportion of the image that is reasonable sharp in focus

- the smaller the aperture you use, the greater the depth of field

Wide angle lenses

- for fitting a large area into your frame

- especially useful for landscape photography or street photography

- almost everything is in focus

Standard lens

- fairly accurate representation of what the human eye sees both in terms of visual angle and perspective

- perceived as more natural

Tele lenses

- great at isolating a subject that is far away

- allow you to photograph subjects from a distance thanks to their magnification

PRACTICAL

I went to the campus to have an offline class on photography.

We learned a lot and took some photos according to references.
