I'm about to start my first shoot of objects on white background. I just assembled my "strobist" setup from different sources.
I have 3 speedlights, 2 shoot through umbrellas, 1 silver, 2 plastic diffusers for the flashes (you know, you plug it directly on the flash), 3 tripods. White seemless background rolled down from my mezzanine (from 2m high) and another couple meters on the floor.
I thought I could try and shoot big objects, cause less people do so when then only have light boxes.
As it's my first try, it would be cool to have some general technical guidelines as well as some suggestions of subjects.

I don't mean to steal your niches or ideas, just a few guidelines would be helpful for the beginner I am.

For example, I don't know if for some objects I should use some kind of stand, hang them from wires, whatever. Seems like only lying on the white paper might not be very flattering for some subjects.

And I'm sure you have a bigger car than mine (I got a little fiat)   

More to the point : If you don't have umbrellas, here's a great place to get them. All prices include shipping. Unbeatable. Seems too good to be true, but I ordered many (too many) times from them. No problem.

BTW, this piece of advice was free   

Ok, ok, you win, I only have a fiat punto (first generation).
 

Wow, that is impressive ! Thank you so much for the link. I'll take time to read it tomorrow (it's midnight here...)
