While I cook the daily evening meal, my wife settles into her corner of our home office where a table lamp casts a strong shadow of her glass of wine on the wall. That's how I got the idea for this image.
Setup
The background is slightly textured off-white art board. A flashlight positioned to the left of the wine glass and below its bowl is shining upward to create the shadow on the right. The bright light reflecting off the background creates the dark lines that define the edges of the transparent wine glass. A few small reflections of the light source in the wine glass were strategically positioned so they could be easily eliminated during post-processing. The color image was desaturated rather than converted to monochrome (there was so little "color" in the scene that this was one of the very rare situations when I advocate desaturating rather than converting using a color filter).
