i remember making my own camera in the mid 1970s. the lens was one of those crappy macro things you could screw onto a proper slr lens, and the film was actually photographic printing paper. the body was cardboard and tape, and the shutter a bit of cloth.
after you had taken a pic, you had to rush into the darkroom, develop the paper and then reverse print it (cannot remember how, or even if i did).
all a bit weird, but it kept me amused back then. i haven't been involved in photography for nearly 40 years.
If you want to get this effect quickly without spending any money at all, and you have a pro-type camera with a removable lens, you can get it by just holding the lens against the opening, and rocking it side to side a little.
It's a pretty common trick photographers and videographers use to get a sort of dream-sequence effect.
What's the name of the song?

With mere hours of experience in the art and science of optical design, the team at SUPERCHROMAT remain novices in the field. As such, this prime lens, with 6 elements over 4 groups, provides inferior optical performance at a price affordable to few.
Regardless of whether it’s a matter of selective focus in the close-up range, high-contrast available light applications or landscape shots with immense depth of field, this lens fails to deliver persuasive arguments in nearly all situations unless stopped down to f/22.

I totally love this from a DIY creative perspective. You could probably sell this to Zack Snyder for $5m.
Because that's basically what happened in his last 2 abominable movies. He found some really unsuitable thrift lenses and thought it was a master stroke of genius to use them in a professional movie. That's why virtually every single frame is horribly blurred except at the exact center.
At 02:29:50 you can see the shape of a skull form in the plants in the upper portion of the screen.
This is wild, I photograph with a Leica M7. If he sold these lenses, I'd buy one.
Don't forget to make it radioactive!
"...If you're a fan of vintage photography, with all its charming imperfections, the SUPERCHROMAT lens might be your jam. Embrace the softness, the chromatic aberration, the unpredictable vignetting. This lens isn't about precision; it's about character. And at a price only the absurdly wealthy could afford, it'll definitely make a statement. "
The so bad it's actually good :) Lovely song, too
I was challenged to make a lens for a friend without buying any new optical elements. I have a pile of glass that I've salvaged from old camera lenses that I've modified. I wanted to make a cooke triplet but didn't have any negative elements on hand where I precisely knew their characteristics. I then realized that my eye glasses are relatively well characterized negative lenses, so I had an optometrist cut them into a disc shape and I built the lens around that. It performed very well in my simulations, but not so well in real life. But it was a fun project and my friend ended up with a unique lens for her camera.
