I am fed up with just taking bog standard snaps on my camera, I have settings in my menu which I have absolutely no idea what they mean. If I just start on one of the problems that is baffling me for the moment. After going to the menu I select the 'Set' option which opens a drop down style menu, I select quality and then select the highest pixel rate which is 2m. After doing this I then go into the menu again, there is now an option called EV which looks like '+/-' as the symbol. After selecting this it opens into a drop down menu where it is set to 0, now my problem is if I scroll up there are other settings which are +0.3, +0.6, +0.9, +1.2 and +1.5. If I scroll down it reads -0.3, -0.6, -0.9, -1.2 and -1.5. What do these settings mean and when should I use them. Help on this would be greatly appreciated and also it may give me a fighting chance in the photo comp.
