28) What is to force the eg follicle? The use of forced labor is convenient when you have a roll in the film because it does not cover the conditions for photography. Normally, h is often forced to ESRC extreme conditions, as in places where the light is dim, color film and black and white, can be enforced in two ways, first is for Tsar directly by the camera's meter indicating the increase ASA is desired, the second is p or through a laboratory. The amendments will be doubling the ASA equivalent example: A SA 100 pass to ASA 200, ASA 40 0 Pasara to ASA 800 or if you want you can go to an ASA 1600. These increases in sensitivity of the film, will have significant loss of image quality. The black and white films are often forced even much more than color, but comes more enforced will continue to lose more and more quality.

29) Ultrafast Movies: The problem with these films is that they are very hard to get, and its cost increases significantly. Ultrafast films have to give a very clear grain, are often used mostly indoors, in places where light is scarce, also serve to freeze the motion. Usually because they are hard to come by, photographers tend to force the roll at these speeds, but to force the roll seriously damages the film and the image quality.
