Nice job, Don. Your techniques are improving. Try getting a gold colored piece of artist board and holding in out of the picture, BUT so it reflects in the clip and back into the camera. Watch for any possible shadows from the board onto the backgroung and thus in the picture. It should help the clip stand out a good bit.
To hide any reflection of the camera or the opening i front of the light tenk, cut a neat hole into a cardboard and mount this onto the front of the camera lens. Use a compatable color on the cardboard to enhnce the metal reflection, i.e., use gold to reflect in the gold, silver to reflect in the silver/chrome, etc.
