Experience is knowledge acquired over time. It’s knowing exactly what to do with a piece of jewelry….knowing how to style it; knowing the best lighting to use with a colored stone mounted in a yellow gold ring; or knowing how to get the most detail from a diamond by controlling color, light intensity and the direction of light.
Also, every piece of jewelry is different so each piece presents new challenges and rules on the set-up table. For example, a ring with an opal stone requires different lighting than a necklace with diamonds, or a pendant with onyx, or earrings with emeralds, and so on. There is no “one-for-all” lighting set-up when photographing jewelry.
