Can SilverFast 9 SE and SE Plus Save Scans as 48-bit Color TIFF Files?

Many users working with high-quality scans, particularly those digitizing slides or negatives, prefer to save their scans as 48-bit color TIFF files. These files offer superior color depth and are ideal for later editing in third-party applications like Adobe® Photoshop®. Here's what you need to know about saving 48-bit TIFF files with SilverFast 9 SE and SE Plus:

Understanding Bit-Depth

Bit-depth refers to the amount of color information available for each pixel in an image. Higher bit-depths allow for more color gradations, resulting in smoother transitions and more accurate color representation. While 24-bit color (8 bits per channel) is standard for most digital images, 48-bit color (16 bits per channel) offers significantly more color information, which can be crucial for high-quality scans and extensive editing.

SilverFast 9 SE Plus Limitations

SilverFast 9 SE Plus does not offer direct 48-bit TIFF output.
The SE Plus version is limited to 24-bit color depth for standard file formats like TIFF.

Options for 48-bit Color Depth

  1. Use 48-bit HDR RAW:
    SilverFast 9 SE Plus offers a 48-bit HDR RAW option. While HDR RAW files can't be directly edited in third-party apps, they preserve all original scan data. You can later convert HDR RAW files to 48-bit TIFF using SilverFast HDR software.
  2. Upgrade to SilverFast Ai Studio 9:
    SilverFast Ai Studio 9 supports direct 48-bit TIFF output. This version offers the most flexibility for high-bit depth workflows.

Advantages of Ai Studio over SE Plus for your needs

  1. 48-bit TIFF output capability
  2. Multi-Exposure feature for enhanced dynamic range
  3. IT8 calibration for more accurate color reproduction
  4. Advanced dust and scratch removal (iSRD)
  5. Ability to create HDR RAW files for future editing flexibility

Workflow Recommendations

For archiving: Consider using the 48-bit HDR RAW option to preserve maximum data.
For immediate editing: If you need direct 48-bit TIFF output, upgrading to Ai Studio 9 is recommended.

Additional Notes
24-bit files (the standard in SE Plus) are sufficient for many workflows and are widely compatible.
Consider your specific needs and workflow when deciding between 24-bit and 48-bit color depth.
