The laborious transformation from the mundane world into the magical world of the clown.
This was taken about 20 years ago at a camera club photo shoot; one of the club experts set up the situation and the lighting -- studio flash, with light blue and red colored gels. I shot Ektachrome with a 50mm lens on a Canon EF and processed in Unichrome chemistry.
I didn't much like the effect of the colored gels on the whites. Now I have applied a little Photoshop magic to keep only the clown colors.
