Here’s a quick video tutorial on how to use the TWAIN plugin to scan files into Photoshop.

Windows users:

  1. Close Photoshop CS5
  2. Go to this link for the optional downloads and click on the “Proceed to Downloads” button at the bottom, then click “Download Now”: http://www.adobe.com/support/downloads/detail.jsp?ftpID=4688
  3. After downloading the .zip file, locate the file in Windows Explorer and double-click the .zip file to expand it.
  4. Inside the expanded folder is a folder named Optional Plug-Ins.
  5. Inside the Optional Plug-Ins folder is a folder named Win32.
  6. Inside the Win32 folder is the Twain_32.8BA plug-in.
  7. Still in Windows Explorer, drag the Twain_32 plug-in to C:\Program Files\Adobe Photoshop CS5\Plug-Ins\Import-Export.
  8. Restart Photoshop

You’ll likely need to open Photoshop in 32-bit mode in order for TWAIN to work. Here’s how:

  1. Close Photoshop CS5
  2. Navigate to the Program Files (x86) > Adobe > Adobe Photoshop CS5 folder
  3. Double-click the Adobe Photoshop CS5.exe file

To scan files, go to “File > Import” and select your scanner.
