I'm sure this has been covered before, but what kind of set-up do you need to take nice product shots of graphics cards, components etc.? Camera aside (I already have a Canon 500D which I know in the right hands is very capable), what lighting, backdrops, accessories etc. are required? I've been having a look around and am a bit bewildered by the vast array of options. Any advice? I'm not looking for a crazy expensive pro-setup, not least because I'm limited on space, but something that will let me take nice shots.
