Manual camera setting

  1. 1. Manual Camera Setting By Megan
  2. 2. Aperture An aperture is a hole or an opening through which light travels. If an aperture is wide then the image will have a sharper focus only for rays with a certain focal length. This means that there will be an object that it’s more sharper and the background could be blurred. This is called depth of field and this means the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. The aperture also determines how many of the incoming rays are actually admitted and how much light reaches the image plane (the narrower the aperture, the darker the image for a given exposure time). Aperture is also called the f-number. The larger f-number is smaller opening.
  3. 3. Using a 18-55mm lens I thought I'd see how some real narrow D.O.F. compares with real wide D.O.F. F-Stop: f/36 F-Stop: f/11 F-Stop: f/5.6 I have changed the f-stop (aperture) when taking these images. As you can see they are very different. On the left, it shows it is over exposed because there is not enough light. On the right, you can see that it is very dark because I let the light in too much.
  4. 4. Shutter Speed Shutter Speed is a setting on your camera which controls the length of time the shutter is open, allowing light through the lens to the sensor inside your camera. Shutter speeds can go from very small fractions of a second, to several seconds long on most cameras. You will need more time to expose the image when there is less light available and, you will need less time to expose the image when there is more light available.
  5. 5. ISO ISO stands for International Organisation for Standardization. The ISO setting on your camera is something that has carried over from film. ISO deals with the cameras sensitivity to light The higher the number, the more sensitive to light the film is. The lower the number, the less sensitive the camera is to light. The ISO bit is from the standards for film sensitivity, and the number refers to it’s rating.
