This came up recently because there was no glass in the window of the set. All the reflections were to be added in post from photos…. but when the actor stood at the window the Director wanted to see his reflection.
This is a simple trick for a locked off shot. The action is filmed with two cameras one for the main image and a 2nd camera for the refection.
You can find the position of the main camera simply by reflecting the main cameras position in the mirror plain.
Both cameras are equidistant from the mirror and targeted at the same point on the mirror plain.
A line connecting the nodal point ( focal center ) of each camera is perpendicular to the mirror ( at 90° )
If people were meant to see 3D movies they would have been born with two eyes.

Stereoscopic 3D is here to stay. Studios and manufacturers are pushing more shows and fancier tech. While digital workflows, impossible in the early days, mean a better experience for the viewer without the headaches of poorly balanced S3D.
This is an outline of our workflow for a native S3D show. At Lexhag the depth grade is done on the fabulousMistika. For VFX I’ve invested in Eyeon Dimension.
The convention is write equations concisely without the * for multiplication like this:
A w + B ( 1 – w )
This is because hand written algebra tends to use single letters for variables, and multiplication signs can get confused with the variable x. While this form is easier to read, it can be confusing were people are used to reading computer code, and are expecting * for multiplication and long variable names.
