Photoshop JPEG Descriptive Settings: A
Great Guide.
JPEG is universal but the setting indicators
are not. Photoshop has excellent descriptive settings. The
results coincide with the description of Low, Medium, or High. Do some
testing on your own and see for yourself.
- 0 to 2 are LOW, avoid if possible.
- 3 to 5 are MEDIUM, a lot of web images
require this.
- 6 to 7 are HIGH, better settings for
better quality.
- 8 to 10 are MAXIMUM, best settings to
use.
Paint Shop Pro™
is a small graphics
application that I use often. Unfortunately, its JPG setting method is
gruesome by comparison. Paint Shop Pro's JPEG settings range from 1 to
99 with no clue as to image quality.
I use Progressive set to Scan 3 for web
images. This allows the image to build in focus from soft, medium,
to sharp. The Scan 5 setting looks more like a down-loading error.
CompuServe
GIF:
Graphic Interchange
Format.
A great format for saving graphic files.
In this case, Paint Shop Pro™ is my application of choice for
handling GIF files. Especially the GIF
transparent background
color option.
The sample Photoshop menu above has a torn
edge look. This would not have been possible without the GIF
transparent background color option.
A major draw back to the GIF format is its
limited 256
color
range. Ordinarily, photographic images do not
survive such a radical color palette reduction.
I have seen some pictures reduced to a GIF
and they were quite passable. The process can require labor
intensive manual color palette manipulation.
Try it and you will learn a lot about
working with palettes.
GIF animations
using photo realistic images
will demand photo images to be reduced to 256 colors.
