Early color photography required exposures through red, green, and blue filters. The three single-color images were combined, the strengths and interactions of RGB blended into one multicolor image. This "trichrome" technique is still a popular method of capturing infrared light.

The physicist Gabriel Lippmann took a different approach. He was inspired by the phenomenon of light interference, where the phase differences in light waves result in variations of amplitude and intensity. The result is a brilliant spectrum of possible colors:

Many species have evolved to exhibit phase interference - the iridescence of a beetle's carapace or a peacock's feathers is the result of the very same phenomenon that enabled Lippman to create color images in a single exposure.

Lippmann's interference photographs were termed "photography in natural colours by direct exposure in the camera;" a novelty then that now describes practically every color photo.

The result of Lippman's photographic process was a positive image (like slide film) rather than a negative. However, Lippmann plates appear colorless until white light hits them at a certain angle; this light illuminates the interference structure of the photograph, replicating the light shining upon the scene when the exposure was taken. The dark room and single point of illumination you see below is ideal for their viewing.

Later, Lippmann's interference photography technique was expanded with the use of lasers and 3D (rather than 2D) emulsion to create holograms, which capture their subject's light refractions at a variety of angles. White light holograms are viewable under the same conditions as Lippmann's photographs: by shining white light upon them at an angle to illuminate their interference patterns.

My irises. Unfortunately, their black frame is not visible on a black background.

I fucking love optics.

This is a closer shot of a similar picture. The many little fox faces are not in the scene at all. It's a fox face shaped hole I cut in some black paper, stuck upside down on the front of the lens. This shapes the boke - the out of focus blur of a photo. They show up particularly in bright points of light.

This next one for instance is the same scene with the same foxed lens, just focussed differently. When more in focus, hardly any foxes. (except the actual fox skull in the case)

Note a few faint upside down foxes on the top right of the gold edge of the box; foreground boke is the right way up, background boke is inverted. I put the fox on the lens upside down to make the background foxes the right way up.

To make them bigger, all you need is a larger aperture (expensive) or a larger distance from subject to background (easy), like this.

The background of the image is a black piece of paper with a lamp behind it. Each fox is just a hole I punched in the paper with a pin.

I really love optics.

Fata Morgana

a superior mirage caused by warm air resting on patches of colder air in an atmospheric duct that acts like a refracting lens. Objects on the horizon could appear to be mirrored, distorted, or float. This form of mirage could be the reason for the Flying Dutchman Legend.
