If you can do it yourself the field doesn't really matter. Skills required to replicate this are not very unique, specialised or sophisticated for that matter.. Anyone can do this provided some cash and access to 3D printer. The hardest part is to source similar lens as those are very old and uncommon nowadays.

The wide aperture has a really gorgeous effect. I am also a big fan of swirly bokeh , and this lens has a good dose of that too. It is quite similar to the effect of the Helios 40 85mm f/1.5, Zeiss Biotar 58mm f/2 and the Soviet Zeiss copy, the Helios 44.

Fun fact: Even nuclear fusion is extremely inefficient. All other methods of energy production are dwarfed by the energy capable of being produced by black holes. The tidal effects that cause matter to heat up to extreme temps release tons of energy, making a black hole “dyson sphere” of sorts about 60% efficient, compared to nuclear fusion’s ~1% efficiency.

He said about wedding photography. I’m still not sure how good would the still images look in detail, especially for prints.

@@makipri Looking at the video in 4k, the image on the subject seems to be pretty clear, while the background has a decent blurring effect to it. I imagine the hard part is making sure the subject is in JUST the right spot, and doesn't move out of the intended range to really get the full benefit

In theory, the bigger the projector glass the sharper it is when converted to a Full-frame or smaller. Instead of magnifying, it demagnifies. Quality is a factor, but even cheap glass can get reasonable sharpness

@@makipri The nice thing for wedding work is that it will really eliminate any issues with the venue for the formal shots. This would be wholly unique.

I was thinking @Mathieu Stern is going to love this, and here he is!

I thought of your channel when I saw this project! Would love to see a collaboration!

it is mostly because we are watching this at a very low resolution. My guess is that it isnt that good in the realm of 50MP cameras, but for video, even 4K, it is most likely enough.

​@@AlainPilon I watched at 4k on a 1080p 24" screen. The quality was still vastly better than I expected.

@@clonkex that was exactly my point. These resolution are very low compared to what a medium/large format camera can resolve. So while the current setup degrades the image quality, the original image is so big that most of the flaws are invisible in video. But if I placed a Hasselblad in there to shoot a 100MP image, we would see the paper texture for sure. But as I said above, for video it is brilliant!

@@AlainPilon Ah, I think I see what you mean now, though I'm not really sure what "paper texture" you're referring to. So to clarify, you said "watching this at very low resolution". As primarily a gamer and video consumer, I don't consider 4k to be "very low resolution". In fact I would call 4k "very high resolution". Perhaps you're a photographer and your comment made sense, but in combination with the fact that you don't typically "watch" photographs, it just sounded like you were either A) assuming I was watching at low resolution on my phone or whatever, or B) calling 4k video "very low resolution", neither or which makes any sense.

@@AlainPilon my guess is you are into print media? But yeah, 99.99% of people dont even watch on anything above 4k and majority of them watch on their phones. So this really works there.

Like he said, it feels like a dream. I was just speechless taking in some of the shots. I just wish we could see the uncompressed images

Yeah! The boat for example really looked like a miniature model, I love it a lot

@@arunashamal 😂

Waiting, 😀

sahib lberwita vol 2 as a music video maybe ? 🤔 😂😂😂

Exactly what I thought. The tilt shift lens is just a trick in my opinion, not a true miniature effect.

Was thinking about this

it's a very niche usage ...very rarely used and when someone wants that specific effect, they usually rely on post-processing/green screen to achieve it

@@Ezio470 It’s not that niche. You have to think in terms of scale, use ability, and price point. Camera manufacturers still have to sell it and when the Red One and original Ursa was succh a beast on set to handle, this wouldn’t work in large scale productions. The Alexa LF is the closest digital equivalent I believe. But there are a number of film ways to get close to this specially large format going straight to negative. But if you’ve shot even stills large format, you know how much time it takes to actually setup the shot to take it. Not a quick process

@@STDavis-em1df the Alexa LF's sensor is the same size as a full frame sensor... 36.7mm x 25.54mm for Alexa LF vs 36mm x 24mm of standard "full-frame" mirror less cameras... So it's not really going to be anything special for this application. In fact the "medium format" GFX 100 would make significantly more use of this lens with its 43.8mm xx 32.9mm sensor, or better yet a Hasselblad H6DC with a 53.4mm x 40mm

honestly it's not even particularly impractical - movie production rigs can handle something like this quite easily. in fact, this might be incredibly useful for film production.

@@s.i.m.c.a we can repurpose the diy mic project shock absorber in the nuclear reactor for sure 😉

It's called tilt shift

@@igbatious It produces the same sort of effect as a tilt lens, but by different means. The miniturization effect is caused by the depth of field to be much smaller than that of our eyes at similar distances. Our brains interpret far-away subjects having similar focus to the background as "large" and subjects with different focus as the background as "small" as these normally happen when things are far away from us and close to us. Far away things are bigger than they appear and our brain compensates in our perception, likewise really close things just look big because they are so close and the brain compensates. When something that is actually far away appears to have a different focus than the background our brains interpret it instead as something viewed close up, and so our perception is changed to think the subject "must be" really tiny to be so close and yet so small in the frame. Tilt lenses achieve this by laterally rotating the plane of focus to manipulate this look. The lens created here *actually* has the shallow depth of field.

@@joelsmith3473 The tilting *used to be* employed to *counter* the shallow depth of focus, by tilting the focus plane to intersect with the most of the faces in a group photo, or make it parallel with the ground, a table, a wall, or whatever. These days, people know of the tilt lens as a novelty, used for the opposite purpose, to call attention to the effect itself.

@@igbatious it's not called tilt shift

I don’t really see anything to be “miniaturized”

Good idea 👍

Yeah, basically, just add a mount for your camera brand, and voila! (Some engineering stuff needs to happen first, but you get it)

@@DIYPerks 😂

I was just thinking the same about tip-tilt. By adding a way to tip and tilt the lens, the camera could make use of the Scheimpflug principle whereby the focal plane is rotated rather than just moved back and forth. You could take some really interesting and different pictures such as a double portrait with one person near to the camera on the left of the frame and the other person in the distance at the right, then by tilting the focal plane to run diagonally between them, each person could be in focus while everything else in the image is blurred out.

As someone with an engineering degree, college barely prepares you ready to do practical stuff. What he is doing is years of curiosity and practical experience, and a major desire to learn + be okay with failing.

I wonder too, also the glass seems uncoated, maybe because of the whole picture being scaled down at the end point

Maybe it’s the relatively shallow angle through the fresnel lens?

I notice chromatic aberration, but maybe I am imagining things. I saw red aberration in the first shot at the edge of Matt's hair and green aberration on the face of the cow. It is also not a very sharp lens. Typical of the era it comes from, before computer designed lenses ironed out the swirly bokeh and softness, and coatings fixed the low contrast and aberrations.

Chromatic aberration is going to be relatively well controlled at the low resolution of 4k vs a full frame 20 megapixel image.

@@azureprophet my point is that fresnel lenses by default have huge amounts of chromatic aberration, I thought it was gonna be a total disaster but it's pretty much not visible at all!

then he'd have to make a shutter.
