While each implementation is unique, most share several traits: an image editing workstation as the cornerstone, often a database-driven digital asset management system like Media Pro 1 to manage the collection as a whole, a RAW conversion tool like Adobe Photoshop Lightroom or Capture One, and in many cases the software that came with the camera is used as an automated tool to "upload" photos to the computer. The machine itself is almost always outfitted with as much RAM as possible and a large storage subsystem - big hard drives. RAID and external USB and FireWire drives are popular for storage. Most photographers consider a DVD-burner essential for making long term backups, and keep at least one set off-site.
