Photography simply means 'light drawing' from the Greek words. Light stimulates sight and makes things visible. Without light, we wouldn't be able to see anything in colour, therefore it is a vital part in our life.
White Light
White light is made up of 7 colours, Red,Orange, Yellow, Green, Blue, Indigo and Violet. The wavelength of colours/different types of light(UV) changes depending on where they are on the spectrum. Objects are not actually coloured, the wavelength that their surface reflects off creates the illusion of colour.
I experimented with different types of light and the results were really interesting. These photos were taken in a room with the lights off therefore, I had to increase the ISO so I didn't get any under-exposed images. I learnt how to create a spectrum from just a prism and white light. To do this, I had the light and the prism quite a distance apart, as in one of my images below, you can see that it turns out too bright if it is too close. I then got the spectrum that I was happy with and played around with the prism by bending it in different ways to stretch out the spectrum etc. Another thing that I changed was the light itself. I put different colour filters over the light and saw how the colours of the light affected the spectrum. I then had friends that helped me create shadow images. We had a light on a table and were testing out the difference if you were close to the light or far from it. We figured that the closer to the light you are, the mre defined the shadow is. This could help me in photography as I know if I'm trying to create a powerful, sharp shadow, the subject has to be nearby. With the pringles tube experiment, I learnt that translucent paper can affect the way an image is shown. The closer to the tube it was, the more clearer the light image.
