You guys are all so knowledgable. I just took a photography class, so I understand f-stop, ISO and shutterspeed and I am starting to play around with how they all work together. I have a Sony DSC-H10, I guess a bridge camera. I've been mostly playing around in M mode. The one thing I don't get is EV. What is it? I get that is has something to do with how bright or dark the image is. Does it have something to do with the flash. If I am adjusting the f-stop, ISO and shutter speed do I need to adjust the EV? So far I have just left it a 0 all the time. Thanks for all your help. I've been learning a lot from reading through all the different threads.
