How Filmmakers Make Cameras Disappear | Mirrors in Movies: Part II 

Oh, and one has to mention tilt-shift lenses. They allow you to move the image and focus planes to a certain degree, allowing the camera to film a mirror without seeing itself. Truely ingenious technology.

As it happens, the kind of mirror used is called both a one-way mirror and a two-way mirror. I don't think there's any real consensus on which expression is more "proper" to use :)

@@cataleast Aha!! I thought I was going crazy!! That makes sense, thank you haha

Shhh! Just claim the spelling "Fundemental" was a reference to the Dementor :D

rather surprised you didn't bring up the infamous mirror scene from the 1997 film Contact, the one where Jena Malone runs upstairs and into the bathroom and opens the medicine cabinet

Example?

@@Rodutchi Duke Nukem 3d

@@Rodutchi Also many other 3D games made in the late 90s, and also used for reflective ground/ceilings. These days it's mostly either duplicate camera for planar reflection portals, or raytracing, but some games still deploys the same technique for set piece mirrors in linear levels.

Yeah, silent hill 2 on ps2 uses it.

@@Rodutchi Super Mario 64, they have a duplicate of Mario that mimics the player's movement in that room, and it even shows the Lakitu with a camera who's canonically the one controlling the game's camera.

Loved you’re latest vid so much

@@paul_et Super glad to hear that!! Means a lot to me Paul!

GAWX is about to include this effect in a next video I presume >.>

you two are some of the best RU-vidrs on the platform, you guys should collab. please.

@@GawxArt Goats recognising goats!

Exactly! The tools got a lot better but the human eye never lost its acuity for recognizing when something looks off, so real artistry is still needed for how to make it look real.

That's an overstatement for “human eye,” ​"@@DodaGarcia".

Which was in the previous video.

Respect for viewing all those obscure old movies and knowing the techniques they used to overcome the limitations of their equipment!

Masks. Technicians would cut a high contrast litho film mask in the shape of the area to be replaced (where the camera could be seen) then they film using the same setup the replacement shot of either a mat painting or a live action. Then they would make a negative of the mask and make a double exposure of the two film strips, one using the first mask then the other using the negative mask. They used registration pins to keep the masks in position when they changed them but would still sometimes get a black or white line around the mask, so they had to cut a new mask. Sometimes a variable contrast film was used to soften the edge but that had issues as well. Many old films didn't bother trying very hard to hide the mask edge like "A Trip To The Moon" by Méliés 1902 as well as Buster Keaton films. I worked my way through film school making these masks but for color separations for graphic arts printing.

I covered that technique in Part I, if you’re curious

@@paul_et I remember that one. As Contact has for long been one of my absolute favourite sci-fi movies (not just for the mirror scene), I'm so glad you covered it!

I think that was probably done to hide the transition otherwise those huge number of kids will have had to stay perfectly still in-between shots which is difficult to do with that many people. Wobbling the camera makes it impossible to notice if they have moved slightly.

@@sadiporter2966 I thought that was a bit of a fudge. A smooth transition would be more impressive.

​@@sadiporter2966 There is no transition. It's a single shot of the children (projected on to the cupboard)

Yo you were also interested in these kinda stuff🤠

Yep it's so shitty it's insane

That was referenced, but not explained. May you?

When I see smudges on a mirror that gets too much attention, I immediately think the mirror is fake

NOOOOOOOOO

Came here to find this comment. Using her twin added an extra element.
