1. EXPOSURE SETTING
In photography, exposure is the amount of light which reaches your camera
sensor or film.
The main parts of the camera:
Camera body, Shutter, Image sensor, LCD screen, Camera lens, Aperture/
Iris.
- 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.
2. 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.
3.LENS PERSPECTIVE
The are wide angle lens, standard lens and tele lens
Lenses can be categorized by FOCAL LENGTH（the shorter the focal length,
the wider the angle of view and vice-versa.）
DEPTH OF FIELD
The proportion of the image that is reasonably sharp and in
focus.
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.
4. 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
