Format Overview & Applications

The Kodak Professional DCS Pro SLR/n (Nikon F-mount) and SLR/c (Canon EF-mount) were landmark full-frame 14-megapixel DSLRs introduced in 2004. Known for incredible base-ISO sharpness and lack of an optical low-pass anti-aliasing filter, their DRF raw files captured extraordinary landscape and studio detail. Converting DRF to lossless PNG ensures that every ounce of optical sharpness is preserved without lossy JPEG compression halos.

Technical Specifications & Codec Breakdown

The converter parses Kodak Pro SLR container structures, reads linear 12-bit/14-bit CMOS sensor telemetry, applies camera color matrix profiles, demosaics high-acutance pixels, and outputs a standard lossless 24-bit PNG file.

OS & Browser Compatibility

Opens directly in macOS Preview, Windows Photos, Photoshop, Figma, GIMP, and all modern web browsers.

Useful info

Use lossless PNG for architectural and landscape photographs shot on the Kodak Pro SLR/n to maintain extreme edge acutance without compression noise.

Format Comparison & Technical Specifications

A 22 MB Kodak Pro SLR/n DRF raw file transforms into an uncompressed 32 MB lossless PNG master plate in approximately 310 ms.
