Exposure/light metre: is a device which is used to measure the amount of light falling or being reflected by the subject
f-stop / f-number: is a sequence of numbers showing the relative apertures, from which the light travels through to the sensor/film. By changing the aperture it halves or doubles the light
Focal plane: is a point (plane) on which a sharp image is formed
Focal length: is the distance between the lens and the sharp image, when the lens is focused for infinity
Focus: is when an image is clear and sharp
Format/frame: is a term given by a camera for the picture area; i.e.. full frame, two thirds
Flare: is the unwanted light which is scattered or reflected within the lens causing the flare
ISO: is short for 'International Standard Organisation' - it is an indication of how sensitive the film or the sensor is to light
Jpeg: is a file format for compressed digital colour image
Kelvin (K): is the measurement of the colour temperature
Manual focus: the camera may not a function to auto-focus the lens, the user has to manually focus the lens by hand to get the image sharp
Noise: is similar to the term 'gain' used for films. Digital noise produces random scattered pixels all over the final image, usually red and blue pixels
Overexposure: is when the too much light has gone through the lens producing a washed out image
Perspective: to give an image the 3-dimensional depth and show distance
Programme/auto mode: is a fully automatic function on the camera where the camera selects the aperture and shutter according to the light and the camera's built-in programme
RAW: image produced by the camera which is unprocessed. A RAW file is uncompressed and are larger files than JPEG files
Rule of thirds: horizontal and vertical lines used to compose a subject placing the horizon on the top/bottom line
Selective focusing: using a shallow depth of field to focus sharply on a selected object in the scene where the other parts of the image are out of focus
Shutter: thin metal/plastic curtains that are at the back of the camera that allows light reaching the film/sensor
Shutter speed: is the length of time for how long the film/sensor is exposed to light
Shutter mode / shutter priority / TV: is a semi-automatic mode where you choose the shutter speed and the camera metre sets the appropriate aperture
Telephoto lens: a lens made to create relatively large images with a focal length shorter than an ordinary lens
TTL: is referred to 'Through the lens' camera reading, i.e. the exposure reading of the light measured by the lens and the flash
Underexposure: is when not enough light has gone through the lens to expose the image, the final image is dark.
Viewfinder: a preview window that allows the user to frame and focus the final image before taking the photograph
Wide angle lens: are lens with short focal length and are used to give a wide angle view
Zoom lens: is when the focal length of the lens is altered by zooming in and out, it is a lens which goes from wide angle to telephoto
f-stop / f-number: is a sequence of numbers showing the relative apertures, from which the light travels through to the sensor/film. By changing the aperture it halves or doubles the light
