around' resulting in diffusion of sharp lines and loss of definition.
This can be minimized with thinner emulsions and a light absorbing
base under the sensitized layers.
describes an image where most if not all of the subject matter has a
density range from midtones to highlights. A predominantly light
picture.
where color is stored in RGB, YMCK, etc. lines of pixels instead of
bytes or planes. Sometimes called row sequential for a horizontal
raster.
see color models.
describes an image where most if not all of the subject matter has a
density range from midtones to shadows. A predominantly dark pic-
ture.
look-up-table — used to transpose one value into another via some
predetermined scheme.
least significant bit — the right-most bit in a binary code.
assigning colors to particular areas of an image based on shade or
some other description. Often used to produce visually continuous
tone color images when there are very few colors available in the
palette to do so.
an undesirable visible interference pattern created when dot screens
overlap at certain frequencies. This pattern can be eliminated (sub-
dued) through trial and error and compromise. The angles and fre-
quencies of the four process screens must be manipulated to reduce
the effect.
most significant bit — the left-most bit in a binary code.
the process of reading densities through photoelectric conversion.
