How to hide the camera when shooting in front of the glass

First of all, what kind of glass do you look at? If the reflective glass surface looks like a tall building, the machine reflection is not very clear. Polarizers can be used to reduce the reflection of mirrors, which is especially good for glass.

Second, look sideways, no.

The color behind the glass should be as light as possible, and the deeper it is, the more reflective it is.

If you are shooting a short film similar to a movie, you should use something on the street, such as a few passers-by chatting there, which just blocks most of the shots and only exposes them. Photographers and assistants also wear clothes needed for the plot, such as shooting a hospital play. Photographers and assistants also wear white coats, and there is an oxygen bottle and a medical cart next to the machine.

If the reflection is obvious, it is common in Hollywood to buckle the glass and change it into green cloth, and then synthesize it later. We can't do it naturally, but we can analyze the viewpoint reflected by the mirror or glass first, find the approximate viewpoint and focal length range, shoot the required content, and then synthesize it later.
