With the Aldus PhotoStyler 2.0-a Windows-only package-one can convert images from color to grayscale, and vice versa. Photoshop can produce output in many forms and, unlike similar packages, reads and writes CompuServe GIF files. Photoshop also permits independent editing of four-color-process images, and the program's device-independent support allows calibration of output for precise color matching on different printers and paper stock.
Rotate, Stretch, and Distort options let one alter image shapes. “Adjust Variations” permits users to make critical color corrections and adjust the color balance of an image's shadows, highlights, and mid-tones. A gradient tool creates gradient color between foreground and background. Using the Magic Wand selection tool along with “Grow” and similar commands, selections can be refined to use the Quick Mask tool in the toolbox.
The Windows menu contains a series of palettes that can be accessed through the menus or an extended keyboard's function keys. Photoshop 2.5.1 features increased performance over previous versions, and PowerPC users can download or plug-in any of several online services to further increase performance. In our experience, for library applications the most useful features have been the ability to increase contrast when the original has faded and to bring out-or suppress-marginal notes and drawings on a manuscript or document.Īlthough there are at least 14 products available, the two leading products as ranked by Computer User, a trade publication, are described below:Īdobe System's Photoshop is available for both Macintosh and Windows computers. Product capabilities go well beyond what most libraries will need or ever use, but there is almost nothing one may want to do that cannot be done with one of the top-ranked packages.
The focus of this issue is image enhancement products: software which makes it possible to improve the scanned image by changing resolution contrast, masking unwanted information, and removing blemishes. Now that libraries are beginning to pursue imaging on standalone systems and as add-ons to their automated library systems, LSN will begin to track hardware and software for these applications.
