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.)

Kind of like a new twist on this.
(That was a real product. I wouldn't dare use it today.)

The French eBay lot came with two brass petzvals, a 150mm one and a 450mm one.
The 150 was a useful match for medium format GFX, as a long portrait lens.
The 450 is a match for my Abracam 16x16” ultra #largeformat as a normal angle lens. Tomorrow I will mount the adapter that I made and test it.

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?

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 🤯:

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.

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.

Me, posing with my creation, the Abracam.
A 16x16" #LargeFormat camera, with Wollensak Vitax 16" f/3.8 mounted.
Digital screen hangs off lens hood which helps me focus when doing a self-portraits.
No helicoid, no bellows, so focusing is done by moving subject, a millimeter at a time. 🤣

This Nikkor 75cm 1:9 was hard to mount and its focal length makes it unwieldy.
After all that work, the image will end up mostly noise, as the long focal length makes me lose nearly all light after the long indirect bounce. Even with speedlite at max. I think it needs sunlight. (Ultra #LargeFormat)

My first macro #photography with my Ultra #LargeFormat Abracam.
I mounted the 300mm Petzval 78cm away from the screen, giving me ±49cm subject distance, and hence a larger-than-life projection (face almost covers the entire 16" image height.)

The widest I've gone on my Abracam Ultra #LargeFormat:
Hermagis Anastigmat Serie L 1:4.5 210mm
Severe vignetting, of course, but I am not willing the shell out $$$$ for a Super Angulon 210mm.
Also: Vancouver should stop giving away car parking for free.
