SYSTEMS WIDE SCREEN PROJECTION

From Table No. 101, pages 2002010, we note the following:

1- It is not necessary that the imaging takes place in preparation for viewing on the wide screen with the use of Anamorphic lenses to compress the image. Rather, the imaging may take place with a machine in which the ratio (width-to-length: camera window) = (4:3) i.e. with the Academy Aperture or The maximum aperture of the camera window is Full Screen Aperture, while we see the image on the screen at a ratio of 185:1, just because the ratio (width: length) of the projector window = 185:1, as shown in the first case of the table.

2- If the image (on the negative flag used in the camera) has been compressed by the Anna Mor Vic lens, it is necessary to unqueezing or rectifying this pressure in any of the following two stages:

(a) During optical printing to obtain the positive print film that will then be displayed on the screen, and the amount of expansion of the positive image during printing is equal to the amount of pressure obtained by the image during imaging, as is the case in the Super Technirama method. In this case, the positive image is not re-individual during illness.

(b) Or, the negative image may be repositioned while the positive film is displayed on the screen, and this means that in this last film the positive image is also compressed. This is as seen in the case of CinemaScope when the 35-million negative image is touch-printed on a 35-million-positive film as well. In this case, we find that if the negative image was compressed in a ratio of 2:1 during filming, it will be re-straightened during viewing at a ratio of 2:1. .

3- If the negative image re-straightening will be done by means of the projector lens (for example, by a ratio of 2:1) and the ratio (width: length) of the projector window = 1.175:1, then it will follow that the ratio (width: length) of the image will be Displayed on the screen, the Aspect Ratio is equal to the product multiplied by: the window ratio of the projector X the ratio of the image spread by the lens of the projector. For example, we find that this ratio =
(1:1:175) x (1:2) = (235:1) We see several examples of this in the table.

4- The negative image may be compressed during imaging using an Anamorphic lens (for example, by a ratio of 1.25:1). However, the positive image is recompressed once again during the optical printing of the negative image on the positive film, as is the case in the Ultrapanavision method in which the Filming on a 65-mali negative film, then it is printed optically with a reduction on a 35-mali film, then the positive image is compressed again at a ratio of (1.6:1). In doing so we see that the total pressure Anamour is in you

In the negative and positive phases = (1,25 : ) X (1:1,6) = 1:2 .

This calls for the necessity of re-straightening the positive image during the stage of displaying the positive film on the screen, and it is obvious that the re-straightening at that time should be at a ratio of 1:2 as well. If the ratio (width: length of the projector window = (1:175:1), then by multiplying this ratio (x) (2:1), the ratio of the final image seen on the screen = 1:33:01. 35 mm and next to each image there are 8 perforations, i.e. with a double frame, as the negative image is compressed in a ratio of 1.5:1 with an Ana Morphic lens during imaging, then the positive image is compressed again during optical printing (with the reduction on a 35 mm film that carries 4 perforations next to each Image) and the new pressure: Thus, we see that the product of multiplying the ratio of the two pressures (negative and positive) = (1.5: 1) X
​​​​​​(133:1) = (2:1), which calls for the necessity of re-straightening the positive image while showing the film on the screen, and the amount of spreading is = 2:1. If this new ratio is multiplied (2:1) by the ratio of The width to length of the projector is (1.175), which results in the image appearing on the screen at a ratio of 2.35:1.

(e) In some cases where imaging is done without anamorphic pressure, such as the Todd A method, and contact printing of the negative image is done on the positive film without pressure as well, then we see that the marks shown on the round glass markings in the view finder are the size of their borders Exactly equal to the size of the window borders of the projector. It is in equal condition
​​​​​​(1.913 X 868.0) of an inch (i.e., in a ratio of 2.2:1). And so on.

We see that the method that led to a wide image on the screen was then based on photographing a wide image with the camera (without Anamor Vic lenses) and then displaying this diseased image through a projector that also has a wide aperture.
And the same size.

(6) It is noted that the camera aperture window size is always greater than the size of the borders of the marks shown on the round glass marking in the viewfinder.
