Help for my licence film?
Posted 13 November 2007 - 09:54 AM
I recently found this community, and I am really fond of it. I found a lot of answers here, but now I would really like some more help from you.
I am in prep for my final student film, and this is going shot on 35mm stock. The thing is that I am making a thesis about visual effects (masks, rampings and different filters) and I need to implement these things in the movie.
I have a shot like this: A man looks at himself in the reflection, and when he turns around and leaves, the reflection stays there. I thought about shooting it with masking, but it would be extremely hard for the actor to synchronize himself between the takes (one for himself and the other one for the reflection). Then I thought about making this in post; shooting both situations and then just masking it out in the lab.
Do you guys know how this works? Can it be done optically? The movie is shot in 35mm and then projected in 35mm - no digital process involved here (due to my student budget).

If the foreground actor doesn't actually cross physically in front of the mirror, the two halves can be composited in-camera with a split-screen. That doesn't solve how they will time themselves to each other though. Maybe some sort of video tap could be used in the camera to record the first half's action, then play it back in a monitor for the second half's actor to see while they look into the mirror. The trick would be to find a way to start at the same point of time. This would be easier if you could marry the two pieces of film using dupes in an optical printer, not in-camera.
Of course, the easiest thing would be to hire twins and build a fake mirror set (glass instead of a mirror with a mirrored version of the same room visible through the glass.)
The other possibility is to make the mirror a projection screen instead and rear-project the image of the man onto it, and have the actor match his own movements in the foreground. This would allow you to have the foreground actor cross in front of the mirror.
Otherwise, if you can't do a simple split-screen, you get into the world of travelling mattes (matting the foreground actor against the mirror background), which you can't do in-camera, and doing it in an optical printer is very difficult.

I want the reflection to just stay and watch for a couple of seconds, and then cut. Nothing fancy, just need to use some sort of masking.
I figured it would be better to do this in the laboratory than having to match "frame accurate" the actors' move up to the point in which he leaves or just watches.
My question was if you guys know whether this is possible to do in the lab or if I am stuck with the mask filter option. I would like to be able to shoot both versions full frame, and using only half of each in the final shot.
David, you were saying something about the actor leaning out of the reflection. That can be done, no problem there. The camera will be in lock-off position, so no motion tracking is involved. Also there is no superimposing involved between the character and his reflection. But can I link the two shots together in post production, without using film printing?
In this region the film printing option is... out of reach, at least for a student like myself.

I did a movie with some simple optical printer split-screens:
However, it still takes some skill with an optical printer to do these sorts of splitscreen effects, and your camera needs rock-steady registration and the camera itself has to be rock steady.
If you did a split-screen in-camera using double-exposure, then you'd have to use masks in front of the lens for each half of the split.

I have obtained an Arri 535 for this project, so I don't thing I will have any problem with the registration. Or at least I hope I won't.

I can't wait to shoot it. I'm starting the shoot monday, and until then I'm going to be on set, prepping.

I masked one half of the frame and shot the other side, and when I was satisfied with the take I changed the mask with the one for the other half, and did the same thing for the other side.
Now I had 3 takes for the right side of the picture and one for the left one.
I went to Kodak Cinelabs Romania and processed the film, then asked for an inter-positive for the good takes. With those I went to an Oxberry machine and superimposed the two strips of film.
I wanted to upload the take in divx format, but it's to big. I attatched a single frame.
Thanks again for the ideas.
