You can also import scanned images directly from any scanner that has a Photoshop-compatible plug‑in module or that supports the TWAIN interface. To import the scan using a plug‑in module, choose the scanner name from the File > Import submenu. See your scanner documentation for instructions on installing the scanner plug‑in.
If your scanner does not have Photoshop-compatible scanner driver, import the scan using the TWAIN interface.
If you can’t import the scan using the TWAIN interface, use the scanner manufacturer’s software to scan your images, and save the images as TIFF, PICT, or BMP files. Then open the files in Photoshop.
TWAIN is a cross-platform interface for acquiring images captured by certain scanners, digital cameras, and frame grabbers. The manufacturer of the TWAIN device must provide a Source Manager and TWAIN data source for your device to work with Photoshop.
You must install the TWAIN device and its software and restart your computer before you can use it to import images into Photoshop. See the documentation provided by your device manufacturer for installation information.
