INDEX
91
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.
Advanced Option: This option is displayed whenOutput | Raw file (p. 88) is set.
Output | Raw save film
(Professional Edition only)
If this option is set, then the film corrections are done before the raw file is written.
The Output | Raw output with (p. 90) is also implicitly set to "Save", which means that
the rotation and infrared cleaning are also applied to the raw file.
Advanced Option: This option is displayed whenOutput | Raw file (p. 88) is set.
Output | Raw compression
(Professional Edition only)
This specifies whether to use compression when writing the raw file.
Compression of the raw TIFF file will not cause any loss of image data. It will take a
little longer to read, and especially write, as the algorithm is computationally intensive,
but can reduce total file size by as much as 40%.
The default setting is "Auto", which enables compression for files with 12 or fewer bits
per sample and disables compression for files using more bits per sample.
Advanced Option: This option is displayed whenOutput | Raw file (p. 88) is set and
whenOutput | Raw DNG format (p. 91) isn't set.
Output | Raw DNG format
(Professional Edition only)
This specifies whether to write raw files in DNG (Digital Negative) format. This allows
VueScan's raw files to be read by the Adobe Camera Raw plugin or other programs that
read DNG files.
These DNG format raw files can also be read by VueScan when you set Input | Source
(p. 50) to "File".
Advanced Option: This option is displayed whenOutput | Raw file (p. 88) is set.
Output | Description
This field will be written to TIFF files and JPEG files as an EXIF field and in OCR text
files at the top of the page. You can use it to indicate a one-line description of the image
being scanned.
Basic Option: This option is displayed when at least one of the output files is enabled.
