About BAY to PSD Conversion
PSD (Photoshop Document) is Adobe Photoshop's native file format, supporting layers, masks, adjustment layers, and extensive metadata. Converting Casio BAY RAW files to PSD produces a Photoshop-compatible file with the demosaiced photograph as the background layer, ready for immediate editing in Photoshop, GIMP, Affinity Photo, or any PSD-compatible application.
This conversion is particularly valuable for photographers who want to edit legacy Casio QV or Exilim photographs in a professional image editing workflow. The PSD format preserves 8-bit or 16-bit color depth and supports ICC color profiles, giving you a solid starting point for retouching, compositing, and color grading the converted Casio RAW data.
Why Convert BAY to PSD?
PSD is the industry standard for professional photo editing. While Photoshop can import some RAW formats directly via Adobe Camera Raw, it has no support for Casio's BAY format. Converting to PSD creates a Photoshop-native file that opens instantly without any import dialog, preserving the full demosaiced image as an editable layer.
The PSD format also serves as an excellent archival format for edited photographs. Once converted from BAY to PSD, you can add adjustment layers, retouching, and compositing in Photoshop while maintaining the original pixel data on the background layer. This non-destructive editing workflow is not possible with JPEG or PNG, making PSD the preferred format for images that will undergo significant post-processing.
Common Use Cases
- Open legacy Casio QV-series photographs in Adobe Photoshop for professional retouching and editing
- Prepare Casio Exilim RAW files for compositing workflows in Photoshop or Affinity Photo
- Create layered PSD files from Casio camera output for non-destructive editing workflows
- Convert BAY files for graphic design projects that require PSD source files
- Generate Photoshop-compatible files from legacy Casio photographs for batch processing with Photoshop Actions
How It Works
The BAY file is decoded through LibRaw via Sharp, demosaicing the Casio CCD Bayer pattern data and applying white balance, color matrix, and gamma correction. The resulting RGB image is written as a flat (single-layer) PSD file with the photograph as the background layer. The PSD uses standard 8-bit per channel color depth in sRGB color space. ImageMagick handles the PSD encoding, producing a file that is fully compatible with Adobe Photoshop CS2 and later, GIMP, Affinity Photo, and other PSD-capable editors.
Quality & Performance
PSD stores the image data without lossy compression, so the demosaiced Casio sensor output is preserved with pixel-perfect accuracy. There is no quality loss from the format conversion. The 3-6 megapixel resolution of Casio BAY cameras is fully maintained. Once in PSD format, you can apply adjustments via Photoshop layers without degrading the original pixel data on the background layer.

Tips for Best Results
- 1Use PSD when you plan to edit the photos in Photoshop — for viewing or sharing, JPEG or PNG is more practical
- 2The converted PSD opens immediately in Photoshop without any Camera Raw dialog
- 3Add adjustment layers in Photoshop for non-destructive editing rather than directly modifying the background layer
- 4For batch editing, convert all BAY files to PSD and use Photoshop Actions for consistent processing
- 5Consider converting to 16-bit TIFF instead of PSD if you need maximum bit depth for aggressive color grading
BAY to PSD conversion brings legacy Casio camera photographs directly into professional Photoshop editing workflows with full quality and layer support.
