Files tab

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

Image units

Use this option to choose the units to use when displaying the image width and height. You can choose mm, cm or inch units.

Image size

Use this option to select the target size of the saved images. This is used to compute the dpi of the saved TIFF and JPEG files, as well as limit the aspect ratio of the crop box when "File|Lock aspect ratio" is set.

Image dpi

If the Image size is "Fixed dpi", you can specify the dpi of the output file with this option.

Image width

This sets the target width of the saved images when the image size option is set to "Manual".

Image height

This sets the target height of the saved images when the image size option is set to "Manual".

Lock aspect ratio

This option forces the crop box to have the same aspect ratio as the image size. If this option isn't set, the dpi of the saved images are set to fit the image within the image size;

Save 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.

If you put "=" into the file name after some digits, the frame number will be added to these digits. For instance, using neg017=.tif and scanning frame 1 will create neg017.tif, scanning frame 3 will create neg019.tif, etc. Note that the frame number is relative to the start of the film strip, not relative to the start of a scanning job.

TIFF size reduction

You can use this option to write files with a reduced number of pixels. For instance, if size reduction is set to 3, then every 3x3 block of pixels in the image will be written as a single pixel, which is the average of these 9 pixels.

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 "Color|File color space".

Save 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.

If you put "=" into the file name after some digits, the frame number will be added to these digits. For instance, using neg017=.jpg and scanning frame 1 will create neg017.jpg, scanning frame 3 will create neg019.jpg, etc. Note that the frame number is relative to the start of the film strip, not relative to the start of a scanning job.

JPEG size reduction

You can use this option to write files with a reduced number of pixels. For instance, if size reduction is set to 3, then every 3x3 block of pixels in the image will be written as a single pixel, which is the average of these 9 pixels.

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 "Color|File color space".

Save 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.

Save raw file

This enables writing raw data from the scanner to a TIF file when saving, previewing or scanning, depending on the setting of "File|Save raw with".

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.

You can reprocess raw scan files by setting "Device|Scan from" to "Disk". This lets you rescan images with different settings, without needing to physically rescan the media.

Raw file name

This specifies the name of the TIFF 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 size reduction

You can use this option to write files with a reduced number of pixels. For instance, if size reduction is set to 3, then every 3x3 block of pixels in the image will be written as a single pixel, which is the average of these 9 pixels.

Raw file type

This option describes the resolution of the raw file, in bits per pixel. It should normally be set to Auto, which defaults to bits per pixel of the scanner.

Raw save with

This specifies which operations in VueScan cause the raw scan data to be written to a file.

If set to "Save", it's written at the same time as other files are written (i.e. after a scan completes or when the Save button is pressed). In this case, the raw file has had infrared cleaning and grain reduction applied.

If set to "Preview" or "Scan", the raw file is written at the same time as the preview or scan. In this case, the raw file has not had infrared cleaning or grain reduction applied.

It's much faster to save the raw file at the same time as the scan, since writing the file is overlapped with scanning the data.

Raw compression

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

Default folder

This is the folder where files are read and written by default.

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.
