Light
When we see an object we are seeing the light that is reflected off of it. Sunlight contains light of every colour and when it illuminates the object we are seeing certain colours of light are reflected by that object, that then travel into our eyes. Red objects reflect red light, and green objects reflect green light. Dark objects reflect less light than bright objects. A photograph is created by capturing the light that is reflecting off of our scene and traveling into our camera, where it is captured by film or a digital sensor.
The three factors that influence natural light are time of day, camera direction and weather.

MY EXPERIMENT WITH LIGHT
Coloured Light
A color gel or color filter (British spelling colour gel or colour filter), also known as lighting gel, is a transparent coloured material that is used in theatre, event production, photography, videography and cinematography to colour light and for colour. Modern gels are thin sheets of poly-carbonate or polyester, placed in front of a lighting fixture in the path of the beam.
Gels have a limited life, especially in saturated colours. The colour will fade or even melt, depending upon the energy absorption of the colour, and the sheet will have to be replaced. In permanent installations and some theatrical uses, coloured glass filters or dichoric filters are being used.

My experiment with coloured light
As you can see from the images shown I have added my own coloured filter to a clear glass prism to create a colour on a transparent sheet. As shown in the images I have experimented with different colours and glass shaped prisms as this will allow me to see a variety of different effects.
