I am basically, a complete idiot. I've had my Canon for about 2 years now, but stuck mainly to using it on automatic settings because I thought 'ugh, can't be bothered working out all these times and apertures and stuff' (I have learnt them, but it's kinda like learning times tables - annoying, and time consuming). BUT THEN SUDDENLY SOMETHING AMAZING HAPPENED. Realised there was a light metre inside the viewfinder. It was a bit of a, 'I could slap myself right now' moment, but there we go, I have a newfound love for my poor camera.
