The technique that I use is a combination of Radiography and Photography. This technique allow you to see the inside dimensions of the subject, just as if you cut the subject in half and were able to look inside.
I started experimenting with Radiographic Photography in 1972 as an X-Ray Technologist in the U.S. Navy. The Inside Design Gallery is a collection of subjects from ballet, skiing, hockey, cycling, musical instruments and a shofar. The penny loafer and high heels were done for a fashion showroom at the Dallas Apparel Mart in 1979.
