Why Merge X3F to PDF?
X3F is Sigma's RAW photo format used by cameras with the Foveon sensor (Sigma DP, SD, and fp series). X3F files capture maximum color detail using Foveon's unique three-layer sensor technology, but require specialized software (Sigma Photo Pro, Lightroom, or Darktable) to open. Merging X3F files to PDF creates a shareable document from your Sigma photos — ideal for client proofs, contact sheets, or photo portfolios.
Each X3F file is rendered and placed as one page in the combined PDF.
