As part of doing a digital media course (basic) we are being required to be able to use almost every adjustment on our cameras , shutter speed , iso , white balance , apeture ect to find these these as and when we need them at a moments notice and too see what effect taking exactly the same shot with different settings has on an image .
A very usefull exercise to you get comfortable with using and adjusting you camera to get the most out of it , playing around with digital costs nothing and opens up a whole new world to used to put it on auto point and shoot .
To know where things are , how to change them and what effect that changes will have on the image is an open door to better photography .
So play around with those settings before you need to "want to" use them .
You dont have to use them but its good to know where they are if you want to .
HAPPY GAMES .
