TWAIN is a software protocol that allows imaging programs, such as Photoshop, to communicate with scanners and frame grabbers. By placing a TWAIN file into the program’s acquire folder, users can access the scanner directly from within the software, streamlining the image acquisition process.
Photographers and digital artists use TWAIN to scan or capture images efficiently without switching between applications. Understanding TWAIN integration improves workflow, saves time, and ensures accurate control over image quality during the scanning or capture process.
