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.
Select a Matte color to simulate the appearance of background transparency.
Set the image quality by entering a value between 1 (lowest) to 12 (highest); selecting Low, Medium, High, or Maximum; or by dragging the Quality slider to the setting you want. The higher the quality, the larger the file size.
In Formats Options, set the format for the image.
Baseline causes images to display line-by-line on the screen.
Baseline Optimized applies optimized Huffman encoding to keep file size as small as possible.
Progressive causes the image to display in multiple passes on the screen. Set the number of passes in the Scans box.
After the image is scanned, it appears in an untitled Photoshop Elements window.
