A cross section of Kiwifruit looks like something in outer space (a nebula or supernova) in this photo taken with ultraviolet light. Or it looks like a close-up of some bizarre animal's eye.

WORLD PINHOLE PHOTOGRAPHY DAY
Sunday April 27, 2025
Some pinhole photographs today for this special occasion. Here is a timed exposure pinhole "selfie" taken with the Thingyfy Pinhole adapter for my Nikon D850.
It works the same way as film pinhole photographs except utilising the digital sensor. There is no lens, just a pinhole (0.2mm) and this gives the picture its unique characteristics: (1) soft infinite focus, and (2) an impressionistic result that works as well in colour or black and white. Since the viewfinder is unable to be used (there is simply not enough light coming through the pinhole to see anything), framing has to be done by trial and error. The length of exposure depends entirely on the amount of light.
I spent yesterday afternoon with my wife and daughter viewing the amazing Christmas display at Union Station in Kansas City. We finished the day with a late lunch at Waffle House...it was a perfect afternoon. To view this display though the eyes of a child must truly be wonderous. Image captured with my Linhof Technika IV camera on CineStill's Dynamic 400 film. Self developed in CineStill's C41 kit. I did my best to balance the exposure...f16 @ 4 secs.
in this 38-minute time exposure, a tree points its way to the North Star, Polaris, which hangs like a star upon the tip of a Christmas tree, one surrounded by bulbs of various colours as they swing, circumpolar, around Earth's celestial pole. Notice how a time-exposure highlights the chromatic differences between the stars: the orange hues of older, cooler suns, the white and blue shades of younger, hotter suns. Notice the greater concentration of star trails in the upper left corner. This is the summertime Milky Way, soon to give way to the less spectacular wintertime Milky Way.
Comet A3 (Tsuchinshan-ATLAS) is here seen as I looked west from Cook's Dock Road on the west side of Manitoulin Island, Ontario, Canada, just after sunset on October 13, 2024. It was last seen by Neanderthals 80,000 years ago. I had to wait for some time for the sky to get dark enough to see it, which I finally did through binoculars. Gradually, I could snap photos of it and the thin layers of clouds didn't move at all so, mercifully, didn't obscure my view. If you look closely, you can see the anti-tail glowing like a faint mirror image of the main tail. The anti-tail shoots out from the nucleus not away from but towards the sun, which, in the photo, is below the horizon. The anti-tail is comprised of large pieces of dust left behind by the nucleus. In other words, the anti-tail shows where the comet has already been!

If you look closely, you might see the antitail, a faint mirror image of the comet's normal tail but on the horizon-side of the nucleus. The bright star in the upper right quadrant is Arcturus, in the constellation Bootes.
The aurora app gave us the alert hours before darkness came on, and what the sky presented during the night of October 10-11 was as spectacular as the May display. But this time, for the first time in my life, I was able to see reds and greens before I consulted the camera! Post-processing brought out a wealth of pastel colours in addition to the expected reds and greens. This series of photos was taken right outside my house on the west side of Ontario's Manitoulin Island.

This is a 31-minute time exposure, my first with my new Canon R8. The brightest trail is Jupiter; just to its right is the orange star Aldebaran in the V-shaped head of Taurus the Bull. Above that we see a cluster of blue trails, the young hot stars of the Pleiades open star cluster, also known as the Seven Sisters. The bottom right quadrant is brighter than the rest of the picture because it's picking up reflected light from the road and lawns. Notice the slight curvature in most of the stars, showing their circular journey around the North Star; the trails on the lower right side are straight because they're at the celestial equator.
