Introduction to photography




The first part of the lesson was spent watching a television documentary named "fixing the shadows". This show investigated the early origins of photography. It explored how two different methods were created in a very short space of time, and how one method triumphed over the other.

The second section of the lesson was a chance to begin to understand how shutter speed and aperture can affect the outcome of a photo being taken. For a sharp shot, the shutter speed has to be fast with the aperture low. If you were to do the opposite, the shot would be blurry and over exposed. when setting the aperture, if you have a larger F-stop, the lens size will decrease. and if the F-stop is low the lens size will be large. Depending on the size of the F-stop, a different amount of light will be caught by the film when taking a shot.

The final segment of the lesson was used to learn what "semiotics" and "representation" means within photography. "semiotics" is the way we process images we see. It is also thr study of sign systems. "representation" is how some people use different things in order to mean something. An example of how when some sees an image associates it with something is; if you see the word "rose" (this is known as the signifier) you think about a rose flower in picture form (this is known as the signified)
