Been a while, another video for everyone here:
https://www.youtube.com/watch?v=bTzm0VKc0F0
As usual shot with the EOS-M with Minolta MD glass.
Most of the shots with the 100mm bellows.
Others with 50mm and 24mm primes reversed on the bellows. |

Awesome work! I watched the whole thing, several parts more than once.

Being able to see through the red mark was amazing. Is the red mark on a black widow spider the same absence of pigment? |

Thanks everyone.
I'm not sure on the other black widows, I take guess and say yes. The movement doesn't happen often, I first noticed it when scanning through the video at high speed. |

Marc,
That was captivating! I learned a great deal and enjoyed every minute.
[Off-topic for macro: I did a double-take, then a triple-take, at your comet-like star trail time lapse at 8:30. After a bit of head-scratching, decided this might conceivably be done in camera by racking focus and aperture during each exposure. But a bit of checking shows that post-processing tools exist for this. I take it you went by the latter route? Looks great, whichever.]

You're right. I wrote my own script to do the trails, its kind of a progressive lightenIntensity with imagemagick.
I found out later that there exists a program that does the same thing call starstax, look for comet mode. |
