Lol wait till you have a more advanced understanding of meta materials and pseudo/virtual materials

This is the story of your enslavement, are you aware? 👉The Connections (2021) [short documentary] 💖

Honestly thought it was gonna be a video on some high tech new thing and then he's like "it's mirrors!" And I was like oh lol

The simpliest answer is usually the correct answer.

@@815TypeSirius 🤣 there's no translate to english on whatever cryptic riddle this is meant to be. Can you define or link any of your conspiracy theory sounding responses to "the illusion works", or are we going to get a "wait and see" or "a friend of a guy I work with said"?

Best thing, it's not affected by picture angle either. It's just the difference in distance as percentage of total distance that matters. So a camera can be put far away, then use a narrow angle lens in to give the appearance of being close, while still having the same effect as being far away.

I thought that the difference in size was because the line of sight coming from our eyes is never parallel. If the observer is further, the line of sight becomes closer to parallel and the difference in size is smaller. I mean, if you have a beam of light that's exactly parallel, the distance wouldn't matter, it would have the same size regardless of the distance. Does it make sense?

@@Lucas-nf1uq No, it just has to do with the angles the light is coming into an eye or a camera lens. Things will look "smaller" if they are far away - regardless if you look with just one eye. Same thing for a camera. But if you campare 2 similar objects - one that's 2 m away and one that's just 1 meter away, the difference in "apparent size" will be quite big - but not so much if one is 19 m away and one 20 m away - despite the distance between the objects being 1 m in both cases. Even if you look thru a mirror reflecting objects behind you, not much will change as all relative angles are preserved even for reflected light. Same applies, even if the light bounces several times - the relative angles will not change as long as the mirrors are flat. If all relative angles are preserved, there will be no difference if light is coming from far away or if it takes a detour bouncing between mirrors. It's the length of the lights path that counts for how far away objects appear to be - and because of that, the longer light path will cause objects behind this mirror array to appear further away than they really are and thus look smaller. But the detour taken by the light is the same regardless of the distance to the fist mirror (that will be equivalent to the distance between the 2 objects in my fist example) - so if standing far away, the percentage of that "error" will go down. Even with a camera far away that used a telephoto lens that "error" will shrink with distance, because such a lens only makes the camera capture incoming light in a much narrower angle range (and thus can get much more detail within that range), but the relative angles between objects still doesn't change. That way, it's also possible to film with great detail and high resolution, while still make the error pretty much neglectable. The line of sight not being parallell affects our perception of depth (especially at short distances), since each eye will look at objects from a slightly different angle - just like having 2 cameras placed at a slight distance from each other. Our brain then interpret that as a single image with depth perception). But that doesn't matter very much here, since each eye is affected the same way. But that angle difference on the other hand, introduces an error at the edges of the mirror. That will also go down by distance.

@@Speeder84XL , thanks a lot for your patience. I was not referring about one or two eyes. I was just assuming that the apparent size is the angle we see an object, and the distance doesn't matter. Lets assume the object is 2 m tall. If it is 1 m away it will cover 90° of your vision (45° up and 45° down). If the same object is 2 m away it will cover 53,1° of your vision. If you double the distance the apparent size doesn't exactly divede by 2. If the distance is big I think the approximation is valid. The point I am trying to make is that our sigh of view is never parallel and that mirrors set works only for a parallel beam of light. Therefore there will always be a difference in the apparent size if we compare the object behind that "invisibility cloak". The difference in the apartment size will be smaller for larger distances, but the reason for that is the angle, not the "distance ratio".

@@Speeder84XL, I forgot to mention... In the video with the camera fixed at the same distance from the mirrors set... If we put an arm behind the mirrors, the arm will look smaller then it should. Lets say its thickness is the half. If we put a chopsticks behind the mirrors the difference will be smaller, may be just 0.75. I am just guessing numbers. But the idea is that for a smaller object the difference will be smaller because the angle is smaller too. But the distance continue to be the same. I couldn't explain very well, I hope you understand what I mean. I understood your point and it makes sense, but I think we should consider the angle. Thanks one more time :)

The irony of your comment is that he had wall pads behind him in this video. 😏

Thats one of the things I love this channel about the most! c:

Personally I don't think that's a good idea to expose your family on the internet. It has ruined many lives

It's not like he's following them around with a camera 24/7 documenting their lives, just quick cameos as assistants or helpers. Not the family drama types of channels. Relax@@sweetmelon3365

While anonymity exists and is still legal, the internet will still be a dangerous place

Haha, ya think James left the International Brotherhood of magicians in favor of Brigham Young University and the University of Rochester? 😁

@@HelloKittyFanMan. not necessarily Jimbo. But somebody at the University of Rochester

Magicians do use mirrors and mirror boxes all the time but I have not seen this specific setup before. I will comment that this mirror setup requires you to hide the excess mirrors so it may be a bit trickier to use.

@@westonding8953 they go out of their way not to reveal their tricks work also too.... I'm pretty sure I've seen this. I'm pretty sure I've even seen marked down versions of this on like tricks you can buy at magic shops.

​@@westonding8953you can hide it with a plant or some table.

Hah I hear you!

Our meetinghouse growing up had that second set of accordion doors like in the video, but our current one has the second setup you mentioned with the classrooms on the side. Guess they changed the standard design at some point?

My building has the same cultural hall/gym accordion door.

@@garrettjensen5035: (EDIT: OOPS, see the ddit to my main post: I _have_ seen those accordion doors oriented this way.) Oh, they've changed the designs a lot over the decades. But here in Utah I've noticed quite a number of our buildings follow a handful of plans, but then I run into the occasional oddball. The Parleys Canyon building is very much of an oddball; it has all these little odd floor levels and landings, and this weird stake conference stage around the corner from the chapel, opening up into the side of the gym, with its own piano and electronic organ! Nice to see some other Church of Jesus Christ members replying to this, thanks! I think it's really fun that James here is a member with us!

@@Cyberguy42: Oh wait, yes, I HAVE seen these buildings! I was thinking of an older style building for some odd reason. Actually, yes, this is a very common design here in Utah. I don't know what I was thinking!

*allowing us to see beyond (behind) it.

The rally in the stock market is over, but I'm not sure if stocks will recover quickly, continue to fall, or fluctuate in a narrow range for a few weeks, or if things will get worse quickly. I am under pressure to increase my $300,000 reserve.

Reaching out to financial advisors like Julio Castillo who can help you restructure your portfolio would be a very creative option. Personal financial management will be critical to surviving the next difficult times.

It's really important for beginners not to rely only on videos, otherwise they will lose all their money, like I did when I started with these videos here on KZfaq.

I agree with you. With his help, I split my 450-pound portfolio between different markets. During this bear market period, I was able to net a little over $1 million from high dividend yield stocks, ETFs and equities. However, the reality is that you can't do it without a proven trading coach like Julio Castillo.

He is great, he has managed my investments so well and my weekly returns are stunning. Could someone kindly leave their details here?

Magicians do use mirrors and mirror boxes but this setup has a few inconveniences that have to be addressed.

Not perfectly. Even if you managed to turn the whole thing into a reflecting telescope, it's going to magnify everything by the same amount. That's a problem because things right behind the _cloak_ will normally look a bit small and need some magnification, while distant background objects will already look pretty normal, so magnification will make them look large. You couldn't tune it so objects look quite right no matter how far behind they are.

You can't do that laterally as you'd physically hit the mirror. It would cut out of sight abruptly if you were to come in at a downward angle.

Lol

are you talking about the backside of the mirror? Of course it wouldn't reflect anything

Indeed. In the opening shot, for example, you can see (on a monitor, not sure about a phone) that the area inside the mirror as more noise. This means, as post-production effect, that area was selected and color corrected.

@@mattacer No, I posted the timestamp: 1:27 to 1:30. You can clearly see the reflection of the wall in the back in the mirror which is significantly darker.

i think not all the lights in the room are turned on for that shot in the second shot you can see he is top lit

that's how it actually looks. you can easily tell by the noise in the mirror that there was color and brightness tweaking in post for the rest of the footage. the inside of the mirror is WAY noisier than the rest of the image because brightness was brought up a lot digitally

Some others would love to use this to mess with the brains of the cops 😎

Additional requirements: to see the delay "with naked eyes".

The light will get dull

The light will get dull

If you watch at 60fps, light travels 5000km in 1/60 of a second. So the path the light takes would need to be 5000km longer to see a difference of a single frame in video. Probably impossible to set that up unfortunately!

And even then you won't be able to notice the delay, light is unbelievably fast, and mirrors are unbelievably inefficient

I suppose it could work... so long as the enemy only looks at it from directly in front and doesn't consider the 2nd set of mirrors (which have to be as big as the area you are 'cloaking') to be out of the ordinary.

@@Cyberguy42Exactly what I was gonna comment! Only works if you could somehow guarantee the enemy would be approaching from one very specific direction and can only move directly toward or away from cloak

it has zero application. you need to stand in the exact right spot for the illusion to work

You can probably get a good general idea of what a ball mirror would do by Googling "The bean in Chicago"

!

yse

If you don't care that much, just put mirrors on the part of the building you don't want to see. You don't need the *correct* view if all you're going for is "a sky view". :-)

I wonder if that would present all new problems. Like birds, or even planes, being at increased risk for collisions.

@@WastedPo birds already fly into normal glass windows, regardless of type or amount of tint. The reflected light and/or the light from the other side of the glass looks like a place they can go and they're moving too fast to change course if they notice at all. It's a very common thing with glass-covered buildings. I've even seen it down on single-floor mini-mall type places and with houses. They even bash into window screens sometimes. Yes, complete mirrors would and do absolutely make this situation worse for birds.

@@darrennew8211yep. Doing it the way used in this video requires an entire structure the size of the building, outside the building...and requires repeating for any other direction...but each time you repeat you've added this gigantic thing completely blocking all the view from a different angle, so...maybe we don't need invisible buildings, lol.

Hm. If you want a statue where you can't see the back side, it's probably easier to just put a wall behind it, or not make/carve the backside at all, instead of trying to warp light around it.
