2nd Task

Today we looked at the basics of exposure. Look at this site http://en.wikipedia.org/wiki/Digital_single-lens_reflex_camera
for more clarification of how cameras operate.

We established that cameras work by exposing the film or sensor to light. The amount of light depends on the length of time the shutter is open for combined with the size the aperture opens, you can control both of these settings manually but most photographers tend to use the camera on the aperture priority setting ( AV ).
Confusingly, the wider the aperture, the less its 'F' number is!

Your task for the week: Refer to the worksheet if you have problems.
1. Set your camera to its AV ( aperture priorty ) setting.
2. Set up a still life object with something in the background.
3. Take a series of at least 4 images changing the aperture setting from f/2.8, f/5.6, f/11, f/22.
4. Upload your images to your blog ready to show on Monday.
