Photoshop & Photoshop Elements
The Topaz Photo AI plug-in automatically installs into Photoshop and Photoshop Elements. Access it from:
Filter > Topaz Labs > Topaz Photo AI
Photoshop and Photoshop Elements will send the selected image layer straight to Topaz Photo AI for processing and return the processed image back to Photoshop.
Upscaling is not available in the Photoshop or Photoshop Elements Photo AI plugins.
