If you're scanning several images in one go, scan each image once and save the raw CCD data file. You can then re-process these scans in a variety of ways without having to scan the image again. This minimises film handling and is the fastest way to re-process all the scans if you want to try different options.
For batch scanning:
As each image is scanned, files with sequential numbering such as "scan0001.tif, scan0002.tif", etc. will be created. You can change the folder and file names by changing the Output | Raw file name option.
To re-process these raw files:
You may also want to follow the procedure in the Advanced Workflow Suggestions section of this User's Guide for locking the exposure and film base color for the entire roll of film. This will give the best quality scans.
