Alright, I'm sure it's somewhere in this forum on how to do it but I just don't understand most of this talk. I'm trying to do light graffiti with slow shutter speeds and wide aperture. I don't understand that. I have a Canon Rebel Gii 35mm SLR camera and I can't figure out how to set a shutter speed from 5-30 seconds. I think I know how to change the aperture to the widest settings, 32 is as far as it will go up I think. So with that said, how do I set the shutter speed from 5-30 seconds? In fact, I don't have a 5 second, it goes 12346810 and so on. This is confusing to me but I really wanna take some awesome light graffiti pictures.
