Name the primary colours: Blue, Red, Yellow. What are the two characteristics that are specific to primary colours? Primarys make us all other colour hues. No other colours can be mixed to make a colour How do you make secondary colours? Mix primary colours (p+p=s) Name the secondary colours: Green, Orange, Violet How do you make a tertiary colour? Primary and a secondary (p+s=t) How many tertiary coulours are there? Thousands can be seen to the human eye If white is not a colour what is it? All colours collected If black is not a colour what is it? No colour reflected What is a hue? It is a pure colour What is colour saturation? Black and/or White mixed with colour How do you make a tint? Colour with white i.e Pink How do you make a shade? Colour with black How do you make a tone?

Aperture: a device that controls amount of light admitted
 * Glossary:**

Camera Obscurer: a darkened enclosure in which images of outside objects are projected through a small aperture or lens onto a facing surface

Contact Print: a print made by exposing a photosensitive surface to direct contact with a photographic negative

Developer: photographic equipment consisting of a chemical solution for developing film

Exposure: An option on automated cameras in which a computer system inside the camera controls the selection of a correct exposure (ie: the correct shutter speed and lens aperture). Today most roll-film cameras meter directly through the lens (TTL metering) using a small light sensor built into the camera body.

Fixer: Chemical solution used to fix a developed image permanently onto film or a print. If you don’t use fixer then the developed image will vanish when exposed to light. Fixers, commonly hypo, convert silver halides to silver grains which are no longer sensitive to light.

Photogram: A photographic technique of making images without lenses.

Photosensitive: Substance which undergoes a chemical change in the presence of light. Film and paper can be rendered photosensitive through the application of various types of chemicals - typically silver halide crystals.

Pointillism: a school of painters who used a technique of painting with tiny dots of pure colors that would blend in the viewer's eye; developed by Georges ...

Positive: A photographic image, typically a print on paper, in which light areas are correctly recorded as highlights and dark areas as shadow.

Shutter: A type of leaf shutter used on many quality cameras, particularly in the early part of the 20th century, made by German maker Friedrich Deckel.

Texture: the feel of a surface or a fabric; "the wall had a smooth texture"

Transparency: GIF images support transparency, but only at a 1 bit level. ie: you can specify one colour to be transparent, which allows the background to show through. However since only 1 bit of transparency is supported it’s common to see a certain colour fringing around transparent images if the edges of the image are of a colour very different from the background.
