PSD (Photoshop Document) is Adobe's native format for professional image editing. Converting Sigma X3F files to PSD brings the Foveon sensor's extraordinary per-pixel quality into Photoshop's editing environment. This is particularly significant because X3F has extremely limited third-party support — PSD conversion provides reliable, permanent access to Foveon photography in the world's most widely used professional editor.
The Foveon X3 sensor's stacked silicon architecture captures true RGB at every pixel without Bayer interpolation. In Photoshop, this means every pixel contains genuine measured color — a fundamentally cleaner starting point for retouching, compositing, and color grading than any Bayer-origin PSD.
PSD provides full access to Photoshop's editing toolset for Foveon photography. Since Sigma Photo Pro — the only reliable X3F decoder — has limited editing capabilities compared to Photoshop, PSD conversion opens Foveon output to professional-grade retouching, compositing, and creative work.
For Foveon photographers frustrated by the X3F ecosystem's limitations, PSD conversion is liberating. It takes the exceptional sensor output and places it in an editing environment that matches the quality with world-class tools.
The conversion decodes X3F Foveon layer data through color separation, producing true-RGB output without Bayer interpolation artifacts. This is written as a PSD with a single background layer at 8-bit or 16-bit depth. The PSD includes ICC profile and EXIF metadata. Internal compression uses lossless RLE or ZIP. A 15.3 MP SD1 Merrill at 8-bit produces a PSD of approximately 30-45 MB.
PSD uses lossless internal compression, preserving the Foveon's full quality. At 16-bit depth, the complete tonal range from the three stacked silicon layers is available for editing. The per-pixel RGB data — with no Bayer interpolation artifacts — provides an unusually clean starting point for Photoshop editing. Retouching at pixel level reveals the Foveon's unique clarity.
