TIFF is the professional standard for maximum-quality image storage and fine art printing. For Sigma's Foveon cameras — which capture true per-pixel RGB through stacked silicon layers — TIFF at 16-bit depth provides the ultimate preservation format. The Foveon's extraordinary per-pixel sharpness, accurate color separation, and three-dimensional rendering quality are maintained at maximum fidelity.
Foveon photographers choose these cameras specifically for per-pixel quality that no Bayer sensor can match. TIFF is the format that preserves this quality investment completely — no compression artifacts, full tonal range, comprehensive color management — in a format accepted by every professional print lab and archival institution.
TIFF at 16-bit with lossless compression is the highest-quality output from any camera conversion. For Foveon photography — where per-pixel quality is the entire value proposition — TIFF ensures zero degradation of the sensor's unique advantage. Every professional workflow accepts TIFF.
Given X3F's extreme third-party compatibility limitations, TIFF provides the highest-fidelity escape format. Fine art labs, museums, publishers, and archives all accept TIFF. The Foveon's medium-format-like quality is preserved at full resolution in a permanently supported format.
The conversion decodes X3F Foveon layer data through spectral color separation, then writes TIFF at 8-bit or 16-bit depth with LZW or ZIP lossless compression. The SD1 Merrill (15.3 MP effective) at 16-bit uncompressed produces approximately 92 MB; LZW reduces to 50-65 MB. The SD Quattro (19.6 MP luminance) produces larger files. ICC profiles and full EXIF metadata are embedded.
TIFF with lossless compression is the absolute highest-quality X3F output. At 16-bit depth, the complete tonal range from all three Foveon silicon layers is preserved. The per-pixel RGB sharpness, the accurate color at every photosite, and the three-dimensional rendering that defines Foveon output are maintained with mathematical precision. This is the definitive preservation format for the world's most unique sensor technology.
