LECTURE:
EXPOSURE- the amount of light which reaches your camera sensor or film.
Figure 1.0 Type of exposure, 31st May 2021
1.IRIS/APERTURE- control the flow of light entering the lensMeasure by f-stop: less number more brighter ( indicated by 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.

2. SHUTTER SPEED -Exposure Time (in secs)Small plastic sheet that open and close to allow light onto the film or prevent light from reaching the film
Figure 1.2 Examples of shutter speed, 31st May 2021
3. ISO - Light sensitivity of filmThe lower the number of ISO the less sensitive camera is to light and the finer grain.
Figure 1.3 Examples of low and high ISO, 31st May 2021
LENS PERSPECTIVE
Wide angle lens, standard lens and tele lens
Different lenses, different purpose> define by focal length
Shorter focal length, wider the angle of view and vice versa

FOCAL LENGTHFocal length is the measurement (in millimeters) from the optical center of a camera lens to the camera’s sensor.
Figure 1.5 Explanation on focal length, 31st May 2021
DEPTH OF FIELDThe proportion of the image that is reasonably sharp and in focus.
The smaller the aperture you use, the greater the depth of field.
Figure 1.6 Depth of field, 31st May 2021
DSLR -capture image much larger lenses and sensors
SMARTPHONE -very limited size of lens & sensor
