I was playing around with an old Fire King pedestal dish and some grapes the other day. I tried with and without flash and in and out of the lightbox. Of the results, I like this one, which used flash the best. The bowl was set up on a sheet of elevated glass in front of white posterboard. The flash is under the glass and aimed at the white background. A table lamp was placed on either side of the grapes to light them a bit while allowing light to spill over to the front of the dish. I faded the shot slightly in post to emphasize the high-key look.
