Modifying the preview image

Before you scan an image, you can use the Preview window to see the effects of most EPSON TWAIN settings, and to make additional image adjustments.

Clicking the Full Preview button starts prescanning and previews the image. EPSON TWAIN offers two preview methods: Preview and Thumbnail preview.

Preview

When you scan reflective documents or want to see the entire image, use this method.

When the Document Source is set to Flatbed, or the Automatic Thumbnail Preview for Film check box in the Configuration dialog box is not selected, the entire preview image is displayed in the Preview window. The Preview window is the right side of the Manual mode window. See Preview for more details.

Thumbnail preview

Use this method to scan transparent materials. In the Thumbnail preview, EPSON TWAIN automatically locates the frames of the film, applies the Auto Exposure feature to each image, and previews them as thumbnail images.

When the Document Source is set to transparent materials (TPU: Color Neg. Film, TPU: Monochrome Neg. Film, or TPU: Pos. Film) and the Automatic Thumbnail Preview for Film check box in the Configuration dialog box is selected, thumbnail images are displayed in the Preview window. See Thumbnail Preview for more details.
