Digital Picture Orbs: Explaining Unusual White Objects
AI Thread Summary
The discussion centers around the appearance of small white spots in digital photographs, which are identified as internal reflections off lens elements in front of the focal plane. These reflections can occur in all types of cameras, not just digital ones. Their seemingly random movement between photos is attributed to the sensitivity of their positioning on the focal plane, which can change with slight adjustments in the camera's angle or position, particularly when hand-holding the camera. The conversation also includes a light-hearted comment about the spots being ghosts, but the main focus remains on the technical explanation of lens reflections.

They are internal reflections off of lens elements in front of the focal plane. They occur in all cameras, not just digital ones. The reason they seem to move about randomly is because their positioning on the focal plane is extremely sensitive to the position and angle of the camera. If you're hand-holding your camera, it's likely that the camera moves enough from one frame to the next to move these little reflections.

Well, gee, if you watched enough daytime TV talkshows, you'd know they are ghosts or spirits!

Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here.
Here are the predictions of 2024 that did not make it:
Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources)
Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources)

I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up.
It was a long trip to Lima; about 14 hours of airtime...
