Adobe Photoshop 7.0 for Photographers- P4

Adobe Photoshop 7.0 for Photographers- P4: In 1996, a group of self-proclaimed ‘digital’ photographers met together at IanMcKinnell’s studio in Holborn, London, to discuss the formation of a DigitalImaging Group. At first, this was a small gathering of professional photographers.The one thing we all had in common was a shared interest in using computers andtheir potential as a photographic medium of the future.

Adobe Photoshop 7.0 for Photographers- P4 Adobe Photoshop 7.0 for Photographers The Enable Workgroup Functionality options relate to the use of Web Distributed Authoring and Versioning (WebDAV) server technology. This is supported in Photoshop and will allow you to connect to a WebDAV server so that you can have your files shared with other Photoshop users. When a user ‘checks out’ a file, only he or she can edit it. The other users who are sharing your files will only be able to make edit changes after the file has been checked back in again. This precautionary behav- ior ensures that other users cannot overwrite your work while it is being edited. The Recent file list refers to the number of image document locations remembered in the Photoshop 7.0 File > Open Recent submenu. The default number is 4, which I find to be too low – you might want to consider increasing this number. Display & Cursors The display Color Channels in Color option is a somewhat redundant feature as this does not really help you to visualize the channels any better. If anything it is a dis- traction and is best left unchecked. The Use Diffusion Dither option is a legacy from the days when people were trying to run Photoshop on an underpowered system with an 8-bit color monitor displaying only 256 colors. The Use Diffusion Dither option uses a dithered pattern to approximate the in-between colors to produce a smoother looking if not completely accurate color display. It is important to realize that the screen drawing code for Photoshop was revised around the time of Photoshop 5.0, such that the screen display you see is more accurate, but may appear slower than before when performing image adjustments. The Use Pixel Doubling option will temporarily convert the image preview to display a quarter as many pixels when you are making an image adjustment with, say, Levels or Curves or moving a pixel selec- tion or layer on screen. Pixel Doubling will greatly improve screen refresh times, but is not really all that necessary with today’s Macs and PC computers. The Painting cursor displays an outline of the brush shape at its actual size in relation to the image magnification. This is the default setting, although you could choose the cursor to display with a precise cross-hair or with the standard tool icon. The latter cursor display happens to be the default setting under Other Cursors. This is fine when starting to learn Photoshop but for precision work I suggest changing the Other Cursors setting to Precise. Depending on how you configure the Display & Cursor options, the Caps lock key will toggle the cursor display. When the standard paint cursor is selected, the caps lock will toggle between standard and precise. When the precise or brush size paint cursor option is selected, the Caps lock will toggle be- tween precise and brush size. When standard cursor mode is selected for all other cursors, the Caps lock key will toggle between the standard and precise cursor. 130Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. The work space Transparency & Gamut The transparency settings determine how image transparency is represented on screen. For example, if a layer contains transparency and is viewed on its own with the background layer visibility switched off, the transparent areas are normally shown using a checkerboard pattern. The display preferences let you decide how the checkerboard grid size and colors are displayed. If you are working in RGB or Lab color mode and choose View > Gamut Warning, you will be alerted as to which colors are out of gamut. Photoshop represents these with a color overlay, which can be a solid or specified percentage color. Figure 6.4 The transparency display settings are editable. You have a choice of transparency display settings: none, small, medium or large grid pattern as well as a choice of different grid colors. Should you so desire to customize the interface. Units & Rulers Use this preference to set the Ruler measurement (inches or centimeters etc.) and type units used. The measurement units can also be changed via the Info palette submenu or by Control/right mouse-clicking a ruler to open the contextual menu. Double-click the ruler bar as a shortcut for opening this preference window. The New Document Preset Resolution options allow you to decide what pixel resolution ...
