This weekend I photographed a couple of parts in the studio for Tombo Racing. These highly reflective objects are very difficult to photograph since they reflect everything in the studio.
For this Hays racing clutch component, I hung the object on a piece of safety wire inside a white shooting tent. I used a black velvet background since it soaks up nearly all the light. Two side lights added the edge detail and the shadows for the engraved name, and a single low power front softbox behind the camera highlighted the highly reflective surface.
The next shot was for Torco Racing and Tombo Racing. They wanted to show their assembly lube on this Carillo aluminum racing piston. I used a similar setup except that I had to place two large white foamcore reflectors to the camera front to get the even lighting on the round piston skirt. A third white foamcore board over the top of the piston created the smooth even lighting at the top.
Below is a shot from my iPhone showing the studio setup. I shoot tethered to my laptop which really helps, and have a huge 4,000 square foot studio gives me plenty of room to work.
