Shutter:
“A mechanical device of a camera that controls the duration of a photographic
exposure, as by opening and closing to allow light coming through the lens to expose a
plate or film.”
- http://www.thefreedictionary.com/shutter
Automatic mode
“Most modern digital cameras have many pre-set programs for different situations
these include sport, landscape or night time. When you select the pre set program, the
camera automatically configures the settings and focus settings to give you the best
result.”

Aperture:
“A usually adjustable opening in an optical instrument, such as a camera or
telescope, that limits the amount of light passing through a lens or onto a mirror.”
- http://www.thefreedictionary.com/shutter
Scene modes:
“Digital camera exposure preset modes that are optimized for specific types of
images, such as sports photography, night shots, close-ups, portraits, or landscapes.”
- www.pcbargainhunter.com/cameras/glossary.html
Programmed mode:
“Program Mode is the camera setting mode in which the camera's computer
controls all the photography functions (shutter speed, aperture, ISO, focusing, etc.). It
effectively makes your DSLR a point and shoot camera.”
-http://en.mimi.hu/photography/program_mode.html
Exposure: How much light is let into the camera lens. This affects the film, making it
lighter or darker.
Overexposure: Letting too much light into the camera lens, exposing the film too much
and causing the photo to be very bright.
Underexposure: Letting too little light into the camera lens, the film is not exposed to
light enough, causing the photo to be very dark.
Shutter-priority mode
“This setting on a camera allows you to set a single shutter speed, while the
camera varies aperture and ISO to achieve a good exposure. This mode is routinely used
to lock in a long exposure to achieve motion blur in the exposure.”
- www.jamesbrittin.com/glossary
Aperture-priority mode
“This camera setting is used to lock in a constant aperture, while shutter speed
and ISO are varied to achieve the correct exposure. This mode is routinely used when one
wants to select a particulat aperture setting to control depth of field, as in landscape
photography.”
- www.jamesbrittin.com/glossary
Manual mode
“A camera's mode that allows the photographer to over-ride automatic exposure settings,
determining shutter speed and aperture as decided upon by the photographer.”

Image sensor:
“An image sensor is a device that converts an optical image into an electronic
signal. It is used mostly in digital cameras, camera modules and other imaging devices.”
- http://en.wikipedia.org/wiki/Image_sensor
ISO:
“ISO (I.S.O.) is the abbreviation for the International Organization of
Standardization, a governing body based in Europe that provides the standards for a wide
variety of subjects.
For photographers the key standard is Film Speed ratings. In the past this was known as
ASA or the American Standards Association (Now discontinued and replaced by the
American National Standards Institute or ANSI), and you could buy your films in ASA
50, 100, 200, 400, 800 and 1600. There were specialist films that would go higher or use
infra-red although these were generally known as the standard speeds.
Most decent cameras now have interchangeable ISO settings which is especially useful
for digital photography because, as discussed in the previous chapter, you can change the
ISO setting for every shot you take without the need to change film.”

Depth Of Field:
“The distance between the nearest and the furthest objects that give an image
judged to be in focus in a camera.”
- http://Dictionary.com
Sharpness: The preciseness of detail in a photo.
F-stops:
“In optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative
aperture) of an optical system is the ratio of the lens's focal length to the diameter of the
entrance pupil.”
- http://en.wikipedia.org/wiki/F_stops
Lens: The glass that a camera looks through.
