White backgound

[w3bbo]

How do people take a pic (of hardware) with a plain white background?

I have tried an MDF board painted white (comes out grey) and also taking them in a bath (damn reflections). So whats the secret? Any help appreciated.

Its a 400D but as I'm new to cameras (jumping in at the deep end) I still have lots to learn both with the camera and photoshop. I've not messed with the manual settings of the camera as I'm still getting used to the fixed ones (macro etc) so any help anyone can give is hugely appreciated.

I'll try the suggestions thus far. Thx again.
