Unit 57: Photography and Photographic Practice Terminology (P1, P2, M1, M2)Term Explanation of term e.g.

what it is used for / the effect it has on your images

Examples

Shutter SpeedIn still cameras, the term shutter speed represents the time that the shutter remains open when taking a photograph.

ISO ISO sensitivity expresses the speed of photographic negative materials. What ISO denotes is how sensitive the image sensor is to the amount of light present

Aperture & Depth of field (F stop)

Depth of field refers to the range of distance that appears acceptably sharp. It varies depending on camera type, aperture and focusing distance, although print size and viewing distance can also influence our perception of depth of field.

Automatic Exposure

A camera in automatic exposure mode automatically calculates and adjusts exposure settings to match the subject's mid-tone to the mid-tone of the photograph

Manual Exposure In manual mode, the photographer adjusts the lens aperture and/or shutter speed to achieve the desired exposure.

Colour Balance In photography and image processing, colour balance is the global adjustment of the intensities of the colours (typically red, green, and blue primary colours

Composition Composition is the placement or arrangement of visual elements or ingredients in a work of art or a photograph, as distinct from the subject of a work. It can also be thought of as the organization of the elements of art according to the principles of art.

Rule of thirds The rule of thirds is a guideline which applies to the process of composing visual images such as paintings, photographs and designs. The guideline proposes that an image should be imagined as divided into nine equal parts by two equally-spaced horizontal lines and two equally-spaced vertical lines, and that important compositional elements should be placed along these lines or their intersections

Complementary Colours

Complementary colors are pairs of colours that are of opposite hue in some color model.

Analogous coloursAnalogous colours are colours that are adjacent to each other on the color wheel. Some examples are green, yellow green, and yellow or red, red violet and violet. Analogous colour schemes are often found in nature and are pleasing to the eye.

Macro Macro photography is extreme close-up photography, usually of very small subjects, in which the size of the subject in the photograph is greater than life size
