This plant only grew three tomatoes, but I'm happy to have them all the same. This was taken outside in bright sun on dark background, then edited to make the background black. Doesn't it look almost studio light?
I use a MacBook, so I put it into iPhoto and pulled up the "Levels" to take out about 18% of the darkest. The background was already dark (almost black), so that made it all turn to solid black and the tomato was in bright evening sun, enough to keep it all showing.
