Sepia-izer
|
|
==========
|
|
|
|
Lots of IIgs graphics, especially scanned-in images, are grey scale.
|
|
With 16 shades of grey, a reasonable degree of photographic clarity can be
|
|
achieved on the GS. However, grey scale is kind of -- well -- grey. Sepia
|
|
tone is often a much more aesthetically pleasant palette, while retaining
|
|
all the clarity of grey scale. For those who may not know, sepia tone
|
|
refers to a range of brownish tones, from almost black to almost white.
|
|
Many early photographs were sepia tone, rather than black and white.
|
|
Personally, I like sepia tone a lot.
|
|
You can convert a grey scale graphic to sepia tone with most paint
|
|
programs, either by building the sepia tone palette by hand, or by copying
|
|
the palette from a pre-existing sepia tone graphic. The former method is
|
|
slow and difficult, and the latter isn't possible with all paint programs,
|
|
and requires that you already own at least one sepia tone graphic.
|
|
Sepia-izer is another method of converting grey scale graphics to
|
|
sepia tone. Sepia-izer will take any PIC or Apple Preferred Format PNT
|
|
file, and convert the palette of the graphic to sepia tone. To use
|
|
Sepia-izer, simply launch it, and select a file from the list displayed.
|
|
Prompts explain how to navigate to the disk and folder your graphics are
|
|
in. The file SF.GET must be in the same folder that SEPIA.IZER is in when
|
|
you launch it. (SF.GET is a utility which provides the user-friendly,
|
|
point-and-click means of selecting files in Sepia-izer. SF.GET is freeware
|
|
and is available with complete documentation on GEnie and America Online.)
|
|
|
|
Ifs, Ands, Buts, and Watch-outs:
|
|
Sepia-izer is dangerous if misused. It alters your original graphic
|
|
file, rather than creating a new graphic, so be sure your file isn't
|
|
irreplaceable. If the original graphic was not, in fact, a grey scale
|
|
graphic, the result will be a mess. Sepia-izer only works on Apple
|
|
Preferred Format PNT files and SHR image PIC files. Unfortunately,
|
|
Sepia-izer has no capability for displaying graphics.
|
|
I'm not pretending Sepia-izer is worth much of anything (it's
|
|
freeware, by the way). It was really a bored-hot-summer-night kind of a
|
|
project. But _I_ use it and find it worthwhile; maybe you will, too.
