The first version was published in 1935 by Jackson J. Rose as The American Cinematographer Hand Book and Reference Guide. That handbook went through nine editions (1935, '38, '39, '42, '46, '47, '50, '53, '56) before it evolved into the American Cinematographer Manual. The first edition of the Manual was published in 1960. [3]
The photography process was much shorter and simpler compared to painting, in which the subject and even the painter used to suffer. It became relatively easy and cheap to set up a photographic studio, so by the 1870s there were many thousands of portrait studios in Europe and America. [1]
If the distance of a light source is changed in the following distance increments 1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, 45, 64 the intensity will decrease by one f/stop. [3] Notice how each step increases by the square root of 2. In practical terms, it means that if one face in a group portrait is 4 metres from the "key" light and another ...
Extended exposure time of 26 seconds. Exposure value is a base-2 logarithmic scale defined by (Ray 2000, 318): = = , where N is the f-number; and; t is the exposure time ("shutter speed") in seconds [2]
In such situations, where an ortho stereo viewing method is used, a common rule of thumb is the 1:30 rule. [20] This means that the baseline will be equal to 1/30 of the distance to the nearest object included in the photograph. The results of hyperstereo can be quite impressive, [21] [22] [23] and examples of hyperstereo can be found in ...
Hey, man. That list is not unsourced. It's from the same "self-published webpage", that's why I've placed the [1] in the end of two tables! The first section of the article is very sourced. SOURCE STOPS UNTIL [1] APPEARS. All is in that "mysterious self-published webpage" Please, man. Don't undo it again. I beg it!
Typically, compressions using lossless operation mode can achieve around 2:1 compression ratio for color images. [5] This mode is quite popular in the medical imaging field, and defined as an option in DNG standard, but otherwise it is not very widely used because of complexity of doing arithmetics on 10, 12, or 14bpp values on typical embedded 32-bit processor and a little resulting gain in ...
Stop bath is commonly a 2% dilution of acetic acid in water, though a 2.5% solution of potassium or sodium metabisulfite works just as well. [1] Because organic developers only work in alkaline solutions, stop bath halts the development process almost immediately and provides precise control of development time.
