I have been playing with the cheapo imitation “cloud dome” white
plastic bowls for photographing jewelry and I have a question.
When I use a simple white plastic material the source lights are
being filtered through this WHITE bowl. The resultant light that
enters the dome now has a significant YELLOW tint because it has been
passed through a WHITE filter. My digital camera can do automatic
white balancing with a reference white background. i have placed a
simple white sheet of paper inside the dome and “white balanced” the
camera prior to photographing the jewelry. However, if the piece is
yellow gold, the auto balance makes it turn out gray.
What do you other people do to adjust? Do I need a different
material for the bowl? If so, what do you recommend? I have used
both incandescent bulbs and fluorescent bulbs for this.
