My shot list has included for a long time a photo of white wine photographed using the bright-line method of defining the edges of the wine glass. I felt it would make a very bold image and never understood why I had never seen a photo of white wine made in that style. As an example, I reviewed over 1000 photos of white wine yesterday and all but two of them were made using the dark-line method to define the edges of the glass. Of the two that were made using the bright-line method, only one of them was good.
So, I can now finally check this style of photo off my shot list.
You might be wondering why I am making such a big deal of this when I posted a photo of the white wine and Alka-Seltzer made in this style just a couple days ago. The difference between that photo and the photo shown below is that the wine below is completely still. It's the bubbles in the other photo that give the wine its bright color we associate with white wine. In fact, notice in the other photo the areas of wine where there are few bubbles: you have the feeling in those areas that you are looking through the wine to the black background behind it. If there had been no bubbles, the wine would have looked black. The wine doesn't look black in the photo shown below because I took an extra step to display the color of the wine.
Setup
A large continuous-light lamp is pointed toward the subject and camera, shining through a large circular diffuser around a background of black felt to define the edges of the glass with bright light. The tabletop is glossy black acrylic. As always with this method of lighting the subject, a black card with a rectangular hole is placed directly in front of the camera to eliminate flare. A second photo was made with white foam core placed behind the glass, A medium continuous-light lamp lit the board from above and behind the glass. The light reflects off the white board and lights the wine. The two photos were then merged.
