Cross-family format translation: how SIGMA-RAW becomes PSD

The SIGMA-RAW source is interpreted as Sigma Foveon camera captures normally stored as X3F with layered-sensor data, then rebuilt for PSD as a Photoshop document that can contain layers, masks, channels, type, and adjustment data. Renaming the file suffix alone could never accomplish that translation.

Interpreted input - Sigma Foveon camera captures normally stored as X3F with layered-sensor data. Required output - A Photoshop document that can contain layers, masks, channels, type, and adjustment data.

What the SIGMA-RAW source carries and the PSD output demands

SIGMA-RAW

What can fail when SIGMA-RAW specialized file format is interpreted

Foveon development has distinct color and noise behavior that a generic raw description cannot predict.

PSD

What PSD raster image cannot safely promise

Most non-PSD outputs flatten layers, while unsupported smart objects or effects may render differently.

ENGINE

How the PSD writer handles this route

a Photoshop document that can contain layers, masks, channels, type, and adjustment data is what gets written, labeled as image/vnd.adobe.photoshop. Whether that actually opens depends on the receiving application, not on the file extension.

Deciding when SIGMA-RAW to PSD is the right conversion

PSD is the right pick once the next application explicitly lists it as accepted and its pixel-based artwork, scans, and photographs role suits the job better than SIGMA-RAW does.

What changes between the SIGMA-RAW model and the PSD deliverable

  • PSD supports alpha transparency that SIGMA-RAW never had, so any transparent areas in the result are newly created, not carried over from the source.
  • PSD supports an editable object model SIGMA-RAW never had, so structure in the result is newly assigned by the writer, not carried over from the source.
  • Treat SIGMA-RAW-specific metadata fields as optional in the PSD result until you have actually confirmed they survived.

Checking the PSD result before you trust it

BEFORE

Record the SIGMA-RAW evidence before conversion

Compare with Sigma's reference software and inspect color, detail, highlights, crop, and capture metadata.

AFTER

Test the PSD file in its receiving workflow

Open the result in the intended editor and inspect layer count, masks, typography, blend modes, and canvas size.
