X3F at a glance
X3F
Sigma raw support is closely tied to the company's Foveon sensor story, giving X3F a reputation and workflow profile that differ from more mainstream Bayer-centric raw ecosystems.
L16 at a glance
L16
The slug appears in product data with Light-camera lineage, but public documentation is sparse enough that the safer interpretation is a specialist raw grayscale interchange usage rather than a fully published neutral format family.

FAQs
Why convert X3F to L16?
Scientific and medical raw image data where each pixel's exact 16-bit value must be preserved: fluorescence microscopy, remote sensing, and instrument image pipelines.
What changes when converting X3F to L16?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to L16 removes camera raw data.
What should I review after converting X3F to L16?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
