I am still fairly new to photography and was hoping if someone could help me out on lighting... I find that a lot of my photos come out really clean, clear and vivid when I use natural light. I love the effect indoors I can get when the light pours in from the window onto an object, especially on a bright day. When there is no natural light, or the lighting is poor, my photos come out very dull, and still not as good as they could be after adjusting levels/brightness/contrast etc in Pshop. In some light conditions, if I use a flash, it just drowns a photo and it can be totally over-exposed, and if I don't use a flash then the lighting is awful. I'm not familiar with apature (sp?) or shutterspeed settings, though I gather they have some effect on the lighting of a photo? I have also heard people say "I let the camera select the shutterspeed" Could someone explain what this means? The camera I have is a Canon Powershot A70. Anyone familiar with this make/model? Thanks for any help!
