- 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.
