Hey everyone. I've had my Olympus E500 DSLR for about 4 months now and have been using the preset modes for most of my photos. Reason being, simply, and to be perfectly honest, I just didn't know how to properly set the different settings. The main question I have is: what are the advantages of dialing in your own settings instead of just setting the camera to AUTO? Also, can someone please explain ISO, F-stop, metering, and WB in simple terms and explain their relation with each other (as in how changing one will effect the other)? I've been doing some research online but figured I'd ask for some assistance here as well. Many thanks!
