Played with a light box over the weekend and took some quick shots of a few old cameras I have in my collection.  I think I maybe should have use a higher f-stop number.   Anyone have any light box tips?

I used a 18″x 18″ x 27.5″ Photek light tent and two 30W Eiko CFL lights (love the low color temp of these) and two $10 desk lamps from Target.
