  2. 2. Shutter Speedo Shutter speed is the amount of time the shutter stays open allowing light to reach the camera sensor. it is measured in seconds, or fractions of seconds.
  3. 3. ISOo ISO is the number indicating a digital camera sensors sensitivity to light. The higher the sensitivity, the less light is needed to make an exposure.
  4. 4. Apertureo The aperture controls the amount of light that reaches a digital camera sensor. An aperture acts much like the pupil of an eye. It opens wider as light decreases to let in more available light. It gets smaller when light increases to reduce the amount of light entering the eye.o The diameter of an aperture is measured in f-stops. A lower f-stop number opens the aperture and admits more light onto the camera sensor. Higher f-stop numbers make the camera’s aperture smaller so less light hits the sensor
  5. 5. Manual V Automatic Exposure Exposure is the amount of light that you allow to hit an object or area in a photograph.o Manual Exposure is when you o When Automatic Exposure is can select what level of selected the camera will exposure you want your automatically chose the level pictures to have. of exposure.
  6. 6. Colour Balance & White BalanceIf your colour balance is correctthen everything in your image willbe seen on screen, as you see it.If it is off the image will look This shows the original which is more blue and on the right a better picture in which all the colours have mixed making it brighter and more balanced.
  7. 7. CompositionThe arrangement of the main subject,other objects in a scene, and/or theforeground and background.
  8. 8. Rule of thirdso On this image you can see the grid lines that has split the photo into three sections each way. It shows you how the main focus of the image is off to the side, on one of the points instead of being in the centre. This is basically what the rule of thirds consists of.
  9. 9. Examples of Rule of thirds
  10. 10. Analogous colourso Analogous colours are colours that are adjacent to each other on the colour wheel. One is usually a primary or secondary with the others being tertiary. Some examples of this are;o red, red-orange, red-violeto blue, blue-violet, blue- On this picture I too the colours green are all analogous.o yellow, yellow-orange, yellow-green
  11. 11. Complementary Colourso Complementary colours are pairs of colours that opposite on the colour wheel.Examples are;o Red – greeno Orange - Blueo Yellow – VioletIn this picture the green andpurple are the complementarycolours. I took this picture myself.
  12. 12. MacroO Macro is used in close up photography, it enables the user to take close up pictures of smaller objects, allowing you to see the finer details that can’t be seen with the naked eye.O This is a picture that I took myself, you can see all the fine details of the flower.
  13. 13. Depth of FieldDepth of field (f stop) control thedistance from the camera that is infocus.If you have a shallow depth of fieldthe subject at the front of theimage is in focus and anything in I took thisthe background is out of focus.
