This is the nicest shot of the night, via two different cameras that captured the same meteor.

A sunset over highway.
A quick long-exposure smartphone experiment. Made by stacking frames from a short time-lapse video.

What a strange, beautiful shot of Comet Lemmon, now passing through the northwest sky after sunset.
Here you see 2 comet tails (gas and dust), plus the unrelated zigzag trail of a passing meteor. And, inevitably, a couple satellite trails, too. 🧪🔭

There’s more to rainbows than the human eye can see: here’s how a rainbow extends into the infrared and ultraviolet.
Photos:
1. Infrared
2. Visible (obviously)
3. Ultraviolet, and
4. A composite showing how UV is beyond the violet in a rainbow, and IR beyond the red end.

I little bit o exposure for this awesome @gamersnexus.bsky.social documentary about smuggling GPUs into China.
I wish they split it into a series and released one episode at a time to make it more palatable though.

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.
The effect presumably comes from the absence of S-cones in the fovea.

Every lens leaves a blur signature—a hidden fingerprint in every photo.
In our new #TPAMI paper, we show how to learn it fast (5 mins of capture!) with Lens Blur Fields ✨
With it, we can tell apart ‘identical’ phones by their optics, deblur images, and render realistic blurs.
