Hi guys,
As I understood, there are generally two types of films nowadays. The first one is the (super) 35mm films, in which the top and bottom of the frame will be cut, in order to achieve the 2:39:1 aspect ratio.
The other option is to use an anamorphic camera which will stretch frame in order to 'squeeze' the frame later on, which will result in a true 2:39:1 aspect ratio, without wasting any parts of the frame.
However, a friend told me that the 2:39:1 aspect ratio can also be achieved without an anamorphic camera, and also without cropping the frame. It has something to do with 'spherical negatives'.
I tried to look this up on the internet, but I still don't quite understand the whole negative process around 35mm films.
Could anyone elaborate on this?
