I got inspired by this!
Not as pretty as yours, but I still like what came out of my coding experiment in C.

I couldn't wait and tried it out tonight.
Not sure what to think of it.
It is... interesting?
At f/9 it is too slow, and that forced me to shoot at ISO 10K, and crank exposure even more in post.
So it really needs a lot of sun-light, I will try again tomorrow.
Unexpected soap bubbles (not a fan.)

Shoulder-mounted light-bucket!
Kind of like a new twist on this.
(That was a real product. I wouldn't dare use it today.)

When mounting it reversed it seems a little sharper? (Hard to say with manual focus.)

Its bokeh balls are dirty. Are they showing lens scratches?

The BBC micro had to be able to run a Formula1 wind tunnel.
Here is a baby Ross Brawn, the legend himself, using his 8bit micro to run wind tunnel tests for Williams. 🤯

Interestingly, the hidden surface removal was elegantly solved in the decade before that w ray tracing in:

“The notion of quantitative invisibility and the machine rendering of solids”

Arthur Appel - 31 Dec 1966

And unlike z-buf, it worked for pen plotters too. 60 yo computer graphics 🤯:

A fool for sure.

If you want cheap domestic, I think this is the only option. She is rocking it, btw, and the US can use a little more communism and a lot less fascism, anyway.

Thanks. Yeah, a 300mm won’t cover my 16x16 back, not even when focussing close. Hence the vignette. I typically don’t mind it, as it often adds something.

AI and humans make different mistakes. We are not expecting the mistakes that a Markov Chain can make, so we are not set up to deal with it the same way.

To illustrate: your human accountant would not tell you to pay His Majesty's Revenue and Customs with pebbles.

To be fair, pollution must have a very narrow definition, here.

The CO₂ produced by the road trip surely dwarfs the 1hr leaf blower by several orders of magnitude.

I assume the calculation considered unburnt hydrocarbons only?

Oh, yeah, spoilers have polarity!

If you mount them upside down, you turn down-force into lift. No wonder that your lap-times suffered! 🤪

Sometimes I put the camera in the back of my car, and park it. As I like to take pictures of trolley busses. Here is one taken with a 75cm process lens mounted.

Heh... well done... you pre empted my "Well ackshually..."

I still think we should return the meaning to its rightful owner.

Yeah, it is quite the presence, especially when using it as macro, with subject distance < 2f needing a deep back for lens placement at > 2f.

(With subject at 2 times focal length away from lens, and lens 2f away from screen, the projection is 1:1 life-size in-camera.)
