Hi, I am brand new to photography and I use a Cannon EOS 30D. I have a good basic knowledge about how my camera works and how to shoot on manual. I understand how and what the aperture, shutter speed and IOS is. My problem is I have a hard time applying it. My background will be to bright and then my subject looks like a shadow. So I'll take shutter speed down and it turns out blurry because its too slow. So I raise that and raise ISO and by time i get it bright enough its too noisy, And my aperture will already be all the way open. I have tried everything to get the results i want, but it seems when I change the settings its like being at square one and I create another problem. Im not sure if its just because I'm not using good light source and not taking my time to frame a shot or maybe I don't understand aperture, shutter speed and ISO as well as I think I do. Im sure this is a very amateur question but any tips or tricks or advise anyone has to offer I'm all ears Thanks!
