how light works:
Light isn't just made up of a single colour. White light is made up of 7 different colours. When those colours are reflected off of an object, the object appears to be white. The seven colours, and their order, can be remembered by the acronym Richard Of York Gave Battle In Vain - which indicates the colours Red, Orange, Yellow, Green, Blue, Indigo, Violet .
The video below talks about lighting, and what changing the coloured filters shone on an object can do. It also shows you that visual light is ADDITIVE and how the complementary colours in visible light are different to those when using and mixing paint.

Light Experiments:
Light Diffraction and Colour Experiments:
WWW: I managed to capture the light spectrum clearly and was able to see many different visible differences in light by simply using coloured filters and prisms.
EBI: Use a wider range of tools, prisms and lenses to get different styled effects and visual variations.
Focal Length Experiment:
WWW: I managed to find the focal length and change it successfully and also quite quickly.
EBI: Use real life objects instead of templates of numbers.
Shadow Experiments:
WWW: Managed to create a range of projections onto a white wall in a dark room.
EBI: Actually photograph the shadows created by placing objects in front of the projection and light.
Drawing with Light Experiments:
WWW: I managed to slow down the shutter speed successfully to capture a deliberate light movement.
EBI: Try and use this technique in a natural and accidental way so that the effect is more shocking.
