The final of these three infrared images is a glass figurine about 3"X5", with gilded head, mane, tail, hooves and rockers that my wife Betty keeps in a curio cabinet near our front door.
I especially like the specular highlights on this image. I think they give the tiny horse an otherworldly, almost sinister air.
To continue with the explanation of procedure, the usual off set focussing rule for infrared applied, of course, i.e. the infrared image was brought into focus slightly behind the visible image using a reference mark found on the camera lens to compensate for infrared's longer wavelength. But owing to the presence of the opaque lens, proper focus had to be attained before the medical lens went on, since nothing could be seen through the camera's view finder after that.
I used a combination of sunlight and incandescent lamps for lighting, and the film was processed in home made D-76 developer. The prints were made on Oriental New Seagull Select Variable Contrast Fiber Based paper, processed in Dektol.
All in all, taking this film and lens combination designed primarily for medical/technical use and adapting it to pictorial photography was as exciting as it was informative, reminding me that even in the most unlikely places there is often the opportunity to make art...if we only look.
