Adobe Photoshop for Photographers- P4: In 1996, a group of self-proclaimed ‘digital’ photographers met together at Ian McKinnell’s studio in Holborn, London, to discuss the formation of a Digital Imaging 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 and their potential as a photographic medium of the future. | Adobe Photoshop 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 behavior 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 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 distraction 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 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 selection 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.
