We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.
PICTURE PHOTOGRAPHY

The film is now ready to be transferred to the winding reel. The film may be wound directly upon this reel behaving the latter mounted upon a movable stand, or the film may be gathered loosely in a basket and transferred to the cutting room.
If preferred the unpolished film may be taken to the cutting room where it is wound upon a reel. Then using the ordinary rewind it is pafrom one reel to another and polished as it is rewound.
When the film is dry it should, whenever | sible. be allowed to stand for a week or so to ''age." That is. to shrink. This is important when a continuous printer is used. With a step printer, such as a camera combination, green film may be printed with considerable satisfaction, as the error due to expansion is compensated in each frame. However, if our hundred foot length of film has expanded three inches in length, we find that at the end of printing with some continuous printers we have over-run four fra
hat in projection we see the frame line ss the screen four times during the one hundred seconds projection time. With a step printer this error is reduced to one four-hundredth of a frame or about a half thousandth of an inch, and as the error is constant it may be disregarded.
When the film is ready for printing, the negative and positive stock rolls are loaded in such a manner that the celluloid side of the negative will be next to the light aperture of the printer. The positive stock is loaded so that its emulsion
