Thanks, Olaf. I sort of came to the conclusion as well that the pattern was caused by the lighting, but I couldn't decide more specifically than that how I thought it was generated. Could it maybe be an interference pattern between the shadow of the comb and the reflection of the comb? -- Victor
Victor, I don't know exactly. I can tell you that it is there in the original 8MP file as well. I had taken "Teeth" first, utilizing sunlight streaming through the window and the shadow was sharp and well defined. When I took this shot, the direct sunlight was no longer entering the room, so I tried using an external flash (550EX remote controlled by ST-E2) instead. As you can see here, the flash was really too close for the shadows to become as sharp and well defined as the sunlit shot (In the original it is obvious there is plenty of DOF here, so the softness is not due to lack of DOF). My guess is that the "interference-pattern" in the shadows has to do with the lighting: The shadow tells you where the flash was positioned, behind the comb and a bit up, but there is perhaps a reflection of the flash in the surface of the tabletop which is causing that "interference-pattern" - just a guess. --Olaf.dk
Well - all of it! This is a black comb on a white table. The color is achieved quite simply by an orange solid color adjustment layer whose blending mode was set to difference. --Olaf.dk
