VLT – The Virtual Light Table


VLT, the new Virtual Light Table in SilverFast HDR and SilverFast HDR Studio, works as an ideal link to SilverFast scanner software. Having the VLT introduced, the archiving workflow is brought to perfection.Scanner and HDR software combined add up to the SilverFast Archive Suite.

What exactly is the VLT?
The SilverFast VLT is a Virtual Light Table, a kind of image file browser for scanned images. The VLT is used for selecting the desired scans for image optimization in batch mode quickly and well-arranged. The customizable preview function, and the possibilities for image rating and marking facilitate this process.

Archiving Workflow with SilverFast Archive Suite
  • 1. Batch Scanning into HDRi or DNG RAW data format
  • 2. Using VLT to select images for optimization
  • 3. Batch processing of image optimizations
1. Batch Scanning into HDRi or DNG RAW data format
The Archive Suite Workflow is designed initially scan all images and to do the image optimization afterwards. Depending on scanner model and the media to digitize, SilverFast's important tools iSRD and Multi-Exposure may be used therefore. Thus, all image data which is detectable at all, will be captured. An IT8 calibration in advance is recommended. Following a "non destructive workflow", image files should be saved in RAW data format HDRi or DNG. For efficiency, SilverFast's batch scanning capabilities may come in handy. Some scanners are able to automatically digitize whole magazines of slides and negatives. Batch scanning is also available for photos by scanning multiple photos simultaneously from the flatbed. After this first step, all image data is now safely stored on the hard disk.

2. Using VLT to select images for optimization
For image optimization, SilverFast HDR (Studio) is the software. Therefore, the VLT tool is perfect for sorting and selecting images, just like a real light table for mounted slides or film strips. Disk directories are easily imported using a navigation tool. An overview area shows small thumbnails of the images contained in the selected directory. There also is a zoom functionality to quickly view an image in detail. For categorization, color marks and ratings can be added to each image. Using drag&drop, those images chosen for optimization are added to the JobManager.

3. Batch processing of image optimizations
All images will now be listed in the JobManager dialog window as single job entries. Each job can be optimized as needed with the known SilverFast tools. However, the JobManager's great strength is to easily copy tool settings from one job to many others. After all settings have been adjusted, the batch processing of all jobs can be started. SilverFast performs the image optimization and saves the new image files to the hard disk.
