Gerald writes – “Since I saw my first 3D movie, “It Came From Outer Space”, in 1953 I’ve been interested in making my own 3D movies. I got my first 3D camera in 1954, a Bell and Howell Three Dimension Company Colorist, which I still have. I was interested in taking 3D pictures through a Stereo Microscope, but have not seen anything that could do this. The Field Sequential system of 3D movies has brought a new interest in 3D movies. Many of the films originally shown in IMAX theaters are now available in the Field Sequential 3D format. The Field Sequential method of 3D works only on TV screens that use cathode ray tubes (CRT) for the display. It utilizes the two interlaced fields used to display the picture. The TV picture is made up of 525 scanned lines. The screen is scanned twice, once for the odd numbered lines and again for the even numbered lines. These two fields can be separated and one used for the right eye and the other for the left eye of a 3D picture pair.” [via] – Link.
