如何拍攝到好的相片？

角度, it is a preference .... for landscape, the wider the better ... :) but from where
you take the shot, it is how the landscape or object touch your mind, or your heart :) .... so it can tell exactly how you see an object ...
my experience tell me, get down your KNEE, or sit on the ground, can get you a more magnificiant/grand angle .... lens must be 20-28mm wide ...

光暗, it is also important, how you restrict the LIGHT get inside your camera or lens, what is the aperture ? what is the ISO ? when I need a flash ? when I don't need flash ? it is all preferences ... but you need to know what is UNDEREXPOSURE, what is over-blown-high-light ... , what a flash can do ?
when you need a filter (optical) to block light, or create effect ... :)
