Adobe Photoshop 4.0: A demonstation of features.

Computing & Information Services seminar

March 20, 1997, 2-4 p.m., Hewitt classroom


1. Overview:

Description:

"Photoshop is the program of choice on Macs and Windows systems for editing graphics involving photographs and is often used for Web graphics. This demonstration shows what it can do, why it is so popular, and why you've gotta have it!

Disclaimer:

Adobe Photoshop, Adobe Photodeluxe, and various plug-in packages mentiond here are not CIS supported products. Fine print: that means that nobody in CIS is prepared to undertake problem resolution or trouble­shooting on these products.

Goals:

To show Photoshop's look-and-feel, features, and power, leaving you with pointers to more information and the motivation to try it. Examples focus on preparation of screen (Web) graphics rather than printed graphics.

2. Background

In 12 years of Macintosh use, this may be the most amazing program I've used!

version history: 2.0, 2.5, 3.0x, 4.0 (and LEs) for Windows and Macintosh.

cost: software, hardware, training materials, and time to try-try-try.

advice: get a CD with imagery, start with basics, and experiment.

3. Measurements, modes, color models, and formats.

Bit-mapping:

raster graphics screen pixels VRAM dot pitch (mask) (< .3 mm)

Bit depth

8-bit=256 16-bit=65.5 thousand 24-bit=16.7 million

32-bit=16.7M+8-bit masking channel

Colors:

gray-scale duotones indexed color RGB color CMYK color

HSB color CLUT=color lookup table gamma color temperature

Processing effects:

dithering anti-aliasing transparency interleaving compression

animation sharpening color reduction

File formats

TIFF PICT GIF89a JPEG PhotoCD PNG PSD PDF

Bottom line for Web-oriented graphics:

plan for 72 dpi, 256-color monitors, aware of common 216 CLUT.

keep small (in bytes) and fast-loading.

save as GIF89a or JPEG format.

keep a high-quality master file.
