Today was a day to honor thy rainbow: ROYGBIV to help them to remember the sequence of colors in a rainbow: red, orange, yellow, green, blue, indigo, violet. Many forms of airborne water can cause a rainbow including, rain, mist, spray, and dew.
180° Rainbow: Full 180° Rainbow in Oak Forest, Illinois. Photos were taken near sunset on 10/11/2021, published same day.
Photo Set #1 taken with a Samsung Galaxy A71 with the factory Dual Pixel 12MP OIS F1.7 lens and 1.4µm pixels with vDIS=ON.
Winter Sundog: A rare formation of a sundog and halo arc in winter. Photo was taken in the winter of 1982.
Photo #2 taken with a Nikon FE camera mounted on a mini-pod through a Nikon 26 mm lens, filter=NONE, Aperture=2.8 f/stop, shutter-speed 1/15th second, loaded with Fujicolor 400 Color 135 Negative Film processed with C-41 Processing Chemicals, and a Type C Print using the RA-4 enlargement paper process, onto a 4X6″ semi-gloss print.
Infrared vs. Visible Light Rainbow: Photo 3 & 4 are photos are of a rainbow in Oak Forest, Illinois, of a repeat post of the absolute original “Photo Of The Day” (now “Featured Photo”) segment that started Labor Day weekend in 2019. In the segment, I show the difference between a rainbow in an infrared photo by displaying the spectrum they use as compared to a visible light photo. Note that the spectrum is down on the near side shifted over and out of the red spectrum, as the featured rainbows show the results.
Photo # 3 is taken on Kodacolor then ASA (ISO) 100 speed film processed C-41 with a tripod through a Nikon EM with a Nikon 26 mm lens, filter=polarizer, Aperture=22 f/stop, shutter-speed 1/30th second.
