Mask <Amiga-M>
The Mask function is one of the most
powerful features of a computer paint
program. In the world of material
art the ability to mask off portions
of an image is used by airbrush
artists, professional photographers,
printers, and even sign makers. With
the help of the mask function it is
easily possible to separate a person
from any type of background or even
to change the color of the sky from
blue to orange. One of the more
difficult features to master but one
of the most rewarding!
In the first line of this requester
you determine the kind of mask you
wish to use by the two buttons
located at the top of the screen. By
selecting ´Non' you turn all mask
features off. If for example you
want to change only one color in your
image but it is interspersed you
should choose ´One'. And if you
prefer to work with a Color Look Up
Table choose ´CLUT'. To select a
certain color out of the color range,
select ´Hue'. You may also build
masks using ´Value' or ´Saturation'
masks, these masks work using the
selected brightness or saturation.
