What I mainly learnt from this induction is that I am photography illiterate. Although I can see that changing the aperture, shutter speed, ISO and white balance for different conditions improves the quality of the image, I don't know why and most of my images are not very good.

So, to improve my knowledge I have done a little research into what each of the above terms actually means:
- Aperture- refers to the diameter of the opening in the lens, which can be adjusted to control the amount of light that reaches the film/digital sensor. (F-stop)
- Shutter Speed- measurement that determines how long the shutter remains open as the picture is taken. The slower the shutter speed the longer the exposure. Together with aperture, controls the amount of light reaching the sensor. (Fractions of a second)
- ISO- refers to light sensitivity. The higher the number the more sensitive to light. Lower sensitivity requires longer exposure to light, but results in a better quality image, so use the lowest sensitivity you can get away with. (100, 200, 400, 800)
- White Balance- used to compensate for different colours of light. Allows a digital camera to be calibrated to correctly display the colour white.
Hopefully with practice I'll manage to improve.
