Files tab

This tab lets you specify what types of files are written when scanning, and the file names and options for these files.

Default folder

This option specifies the default folder to read/write files. This folder is used if a file name doesn't include a folder name in front of it,

Output raw file

This enables writing raw data from the scanner to a TIF file when scanning. This raw data is completely unprocessed data straight from the CCD of the scanners. The image gamma value is 1.0 when there are two bytes per sample, and 2.2 when there is one byte per sample.

The gamma 1.0 data in the raw file will look dark, but this is normal. This file is seldom useful except to process again by setting the "Device|Scan from" option to "Disk".

Raw file name

This specifies the name of the TIF file used to hold the raw data from the scanner.

Note that you can add a path name to the front of any file name. For instance, you can store the raw scan data on another disk by using d:/temp/scan0001.tif.

You can also use file names like test1234+.tif, which will produce test1234.tif, test1235.tif, etc.

Raw compression

This specifies whether to use compression when writing the raw file.

Output to window

This enables updating the scan window when a scan completes (the preview is always updated when previewing). If you're scanning to raw files or doing batch scanning, you can speed up the process by turning this option off.

Output TIFF file

This enables writing the cropped and processed images to a TIFF file when scanning.

TIFF file name

This specifies the name of the TIF file to hold the cropped and processed images. The default setting of this option is crop0001+.tif, which means to use crop0001.tif, crop0002.tif, etc.

TIFF file type

This option describes the resolution of the cropped TIF file, in bits per pixel. It should normally be set to 24-bits per pixel, since many image editing programs are unable to read TIF files with higher bit depth than this.

If you select 8 bits or 16 bits, the file will be saved in black/white format.

TIFF compression

This specifies whether to use compression when writing the TIFF file.

TIFF profile

This specifies whether to embed an ICC color profile into the TIFF file. This is primarily useful if you're using Photoshop. You can specify the profile to use by setting the color space in the Color tab.

Output JPEG file

This enables writing the cropped and processed images to a JPEG file when scanning.

JPEG file name

This specifies the name of the JPG file to hold the cropped and rotated images. The default setting of this option is crop0001+.jpg, which means to use crop0001.jpg, crop0002.jpg, etc.

JPEG quality

This option controls the quality of the JPG file. Using 100 produces images with few visible JPG artifacts, and 50 results in images with noticeable artifacts, but with much smaller sizes. The default value of 90 produces fairly small images with little visible degradation in image quality.

JPEG black/white

This enables writing the cropped and processed images to a monochrome JPEG file. If you're working with black/white film, this will produce files that are smaller than color files.

JPEG profile

This specifies whether to embed an ICC color profile into the JPEG file. This is primarily useful if you're using Photoshop. You can specify the profile to use by setting the color space in the Color tab.

Output index file

This enables writing the cropped and processed images to an index file when scanning.

Index file name

This specifies the name of the BMP file to hold the index print. Each cropped image is added to the index print from left to right, top to bottom.

Index frame

This option controls the placement of images in the index print. If zero, the images are added from left to right, top to bottom. If a number, the images are added at that frame position (1 is the upper left, 2 is the frame to the right, etc.).

Index width

This is the width of an index frame, in pixels.

Index height

This is the height of an index frame, in pixels.

Index margin

This is the margin around an index frame, in pixels.

Index across

This is the number of index frames across in an index file.

Output log file

If enabled, VueScan will log all data sent and received from the scanners to vuescan.log. This is primarily for debugging problems with scanners, and you should only use this feature if you want to send it with a bug report when a scanner isn't working right and you suspect a problem with the way VueScan is controlling the scanner.
