The idea of exploring the use of a camera obscure came about after I watched a documentary called 'Tim's Vermeer' where the question is posed whether or not Vermeer used optics to create his paintings. I found it intriguing to see how 17th century artist could have used these techniques to capture the image through a photographic lens. This allowed artist to see the way light worked which could otherwise not be seen without optical aid. The light and colour of the image is more rich and saturated than it would be if you were to look at it with your own eyes. I believe this is because of your iris changing the size of your pupil to restrict the amount of light hitting the retina. If the light is too intense, like looking at the sky, your pupil with become smaller and so will let in less light. I am not sure whether this causes brighter colours to be muted or if there is a more technical reason for it. Nonetheless, it is interesting to see how our eyes can lie to us and alter the way we see things in the real world.
