introduction to photography

• In lesson we have started looking at photography and it all started with paper and ink, and you had the artist and photographers using water and flame pipe to dry all the photos to get a clear picture of what was on the photo. You also had artist having a load of papers on a shelf in a line out in the sun, and using a camera but at that time they were called mouse traps.
  I have also looked a simcam were you can change any photo so you can make the photo focused or very blurred, and you can make the photo extremely light were you can not see what it is in the picture, and you can make it really dark where it is just a back photo where you can still not see what is going on in the photo. This is because the aperture does not want to harm the photo so when the there is to much light the aperture shuts to let only a small amount of light in. and when there is not enough light the aperture opens up to receive more light.
  The shutter of a camera controls the amount of time film is exposed to a certain amount of light. The shutter speeds on SLR cameras range from about 4 seconds to 1/4000 of a second.
  Then you have of cause camera shake there is a rule, when you have the camera in your hand the shutter speed should not be any lower then the actual focus length of the lens.Semiotics and representation – the example we looked at was – this is not a pipe, and one series of paintings by French impressionist by Renee Magritte, semiotics is a French word which really means opinions and thought to me, as when someone look at something they will have a different opinion to someone else, everyone has different opinions and reactions to things
