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 #
- 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. - 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
#
- 48-bit TIFF output capability
- Multi-Exposure feature for enhanced dynamic range
- IT8 calibration for more accurate color reproduction
- Advanced dust and scratch removal (iSRD)
- 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.
