My first experiment was to compress the full IR-visible-UV range into one picture, with each of the five channels equally weighted:

Since I plan on using wide spectrum photography for plants, the IR-A channel isn’t particularly useful. This is because flowers and leaves are often nearly uniformly reflective in the IR-A range. So I compressed the visual range + UV-A into one image:

Since many insects have a visual spectrum shifted to shorter wavelengths than we do, I also created a shifted version. A quick way to do this is by replacing red with green, green with blue, and blue with ultraviolet:

Since the color replacements are arbitrary, I made a version that keeps the leaves green by making a version with the green and blue in place and the red replaced with ultraviolet:

In the process of inspecting these images and other variations, I noticed that my ultraviolet images probably have less infrared contamination than I initially thought. That’s good. Now, to try my ultraviolet setup on more subjects…

In college, before video games, we would amuse ourselves by posing programming exercises. One of the favorites was to write the shortest self-reproducing program. Since this is an exercise divorced from reality, the usual vehicle was FORTRAN. Actually, FORTRAN was the language of choice for the same reason that three-legged races are popular. –Ken Thompson, “Reflections on Trusting Trust” 1984

Ah, yes, the joys of FORTRAN.
