would a soft box help, or a light tent? i think that should also reflect. http://www.flickr.com/photos/marcoveringa/

Wilt Reader's Digest Condensed version of War and Peace [POTN Vol 1]  More info | May 26, 2008 09:14 | #8 The black plexi is bouncing light to the surroundings, which are then appearing in the photograph. (Imagine what you would see if a mirror replaced the plexi!) Eliminate the surfaces behind (black felt or background paper) and the plexi will be much better.

Get a piece of clear plexi (not black) and put it on top of something matt black (ie: card, material, whatever..).. You'd get a little reflection, but not as much as you're seeing at the moment AND you'd get the 'floating' feeling that you're looking for (but not as pronounced). Current Kit:

You need to change the background as well, to black. Leave everything not seen in the frame as white. The "float" will still be there, just in black not white.  THis is what you are getting, when you change the background yo will get what is on the right side.( no reflection) Final image...  The black background will also help with the burnt out spots on top of the tomatoes. A light tent will help tremendously. A cheep sheet and a support of some kind is all you need. Dont buy the $100 tents Unless you plan on doing a lot of stuff. Check this link on how to build one... http://www.pbase.com/wlhuber/light_box_light_tent Also dont trust your light meter in times like this. Too much black or white will throw it off. Use it to get a base then open or close down by hand till you get whar you need.
