My approach was to portray the object in the cleanest form with lighting, and composition done completely in camera, and post production for minimal dust spotting. To achieve this I bounced highly diffused lighting off of the surface to create the glow from underneath.
The design of the bowl is perfectly symmetrical. I specifically chose to use a dynamic symmetrical composition with the object. I paralleled diagonals, and locked key features into the 90 degree reciprocals. This allowed me to lock the cut work in the bowl onto the sinister diagonal. An average consumer may not see this, however I am sure the artist that made the bowl would. The design of the bowl is locked and repeated into the composition of the photograph.
