In the link below, the DP or Director or someone in the crew is using this film binocular device thing that I don't know what it's call. I might now what it is but correct me if I am wrong. I think it is used so they can see what the shot will look like before actually filming it. If you could please help me figure out what this device is called and maybe even tell me where you can look into buy them that would be awesome! Thanks.
