LECTURE:
EXPOSURE- the amount of light which reaches your camera sensor or film.
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
3. ISO - Light sensitivity of filmThe lower the number of ISO the less sensitive camera is to light and the finer grain.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.
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.DSLR -capture image much larger lenses and sensors
SMARTPHONE -very limited size of lens & sensor
