Photographic TermsBy Muad Suleman
Shutter Speed Shutter speed is the
nominal time for which a shutter is open at a given setting. What this does to your images it allows more an less light into the camera at a given time, faster shutter speeds give you a stop motion picture where slow shutter speeds give you a motion picture.
ISO ISO measures the
sensitivity of the image sensor. The same principles apply as in film photography – the lower the number the less sensitive your camera is to light and the finer the grain the higher the ISO. What this allows you to do is
Aperture & Depth of Field An aperture f/2.8 is wide,
while an aperture of f/22 is small. A small aperture will give you a deep depth of field but on the other hand a wide aperture will give you a shallow depth of field
Manual Exposure You can change either
aperture or shutter speed, once the camera is in the manual exposure mode, the current aperture and shutter speed are shown on the monitor
Automatic Exposure Abbreviated as AE
automatic exposure is a standard feature on digital cameras that will automatically figure our the correct exposure for pictures without any user input other than to select the AE option before taking a picture.
Colour Balance Colour balance is the
adjustment of the intensities of the colours typically primary colours like red, green and blue an important goal of this adjustment is to render specific colours.
White Balance WB is the process of
removing unrealistic colours, so that objects which appear white in person are rendered white in your photo. Proper camera white balance has to take into account the “Colour temperature” of a light source.
Composition Composition also known
as framing is the act of composing the image in the viewfinder, its an visual process of organizing the elements and individual details of a scene into a balanced and pleasing arrangement.
Rule Of Thirds The rule of thirds is done
by aligning a subject with guide lines, placing the horizon on the top or bottom line or allowing linear features to flow from section to section.
Analogous Colours Analogous Colours are
groups of three colours that are next to each other on the colour wheel, with one being the dominant colour which tends to be a primary or secondary colour .
Complementary Colours Complementary colors
are pairs of colors when combines cancel each other out. This means that when they are combined they produce a grey-scaled color like white or black when placed next to each other they give the strongest contrast.
Macro Macro photography is
extreme close up’s photography usually of very small objects and organisms in which the subject in the photograph is greater than life size
