Today’s weird colors brought to you by ulraviolet light. I captured ordinary yellow marigolds from the garden with an ultraviolet band-pass filter on the Fuji IS Pro UVIR full-spectrum camera. I did not get any hidden patterns from nectar guides. That left things to choosing an interesting false-color scheme. Using auto white-balance in either Aperture or gimp both wanted to give me orange blossoms on blue-green foliage, so I went with it. I used the Levels brick in Aperture to increase the tonal width, plus some tweaks The lens was an EL-Nikkor 75mm N f/4 set at f/11. Exposure 30 sec on ISO 400mm.
