Here’s a 7-minute video in which photographer Dustin Dolby of Workphlo demonstrates how your choice of shooting table influences the resulting lighting when shooting bottles.
Dolby starts by showing the resulting highlight you get when placing the bottle on a “normal” rectangular table and lighting it with a speedlight and stripbox adapter.
The table’s edge presents a barrier for placing the light. Adjusting the position of the light will alter the resulting highlight on the bottle, but they all have the flaw of not having a clean highlight where it meets the bottom of the bottle and table.
Next, Dolby uses a custom-welded rectangular shooting table that’s about the size of a textbook. For a similar solution, you can buy a baby wall plate.
While the issue at the bottom of the highlight has been suppressed a little bit, it’s still not “clean as a whistle.”
Finally, Dolby uses an even smaller circular custom-welded shooting table that fits just a single wine bottle. For a similar solution, you can also use an upside-down cup.
This table allows the highlight to extend all the way down to the bottom of the bottle. To finish the lighting with the one-light setup, you can add a reflector card on the opposite side.
