About DCR to BMP Conversion
DCR is Kodak's proprietary RAW format used by the DCS Pro series of professional digital cameras manufactured between 2002 and 2005. These cameras — the DCS Pro 14n, DCS Pro SLR/n, and DCS Pro SLR/c — were built in partnership with Nikon using the F-mount lens system and featured Kodak's custom full-frame CMOS sensors capturing 12-14 bit Bayer pattern data. Converting DCR files to BMP produces an uncompressed bitmap where every demosaiced pixel is stored as raw RGB data without any compression algorithm applied.
BMP's straightforward structure makes it readable by virtually any application that handles raster images, from basic Windows system viewers to specialized industrial analysis tools. This conversion is particularly relevant when working with legacy Kodak DCS Pro captures that need to be delivered to machine vision systems, forensic evidence platforms, or embedded instruments incapable of decoding modern compressed image formats.
Why Convert DCR to BMP?
BMP files are natively recognized by every Windows version since 3.0, making them the most reliable format for guaranteed compatibility with legacy desktop applications, embedded industrial systems, and scientific instruments that lack modern image decoders. Many quality control pipelines and medical imaging viewers specifically mandate uncompressed BMP input because their firmware cannot process compressed formats.
Kodak DCS Pro cameras were widely used in editorial photography, studio portraiture, and commercial work during the early 2000s. Photographers who still hold archives of DCR files from this era may need to convert them to BMP when submitting images to evidence management systems, industrial inspection tools, or legacy databases that only accept uncompressed bitmap input.
Common Use Cases
- Deliver Kodak DCS Pro 14n editorial photographs to legacy evidence management systems requiring BMP
- Feed DCS Pro SLR/n studio captures into machine vision quality control pipelines
- Supply Kodak professional camera images to forensic analysis software mandating uncompressed input
- Provide DCS Pro SLR/c commercial photography to legacy databases restricted to bitmap formats
- Generate uncompressed reference images from archived Kodak professional RAW files for print verification
How It Works
The conversion reads the DCR container, extracts the 12-14 bit Bayer pattern sensor data from Kodak's full-frame CMOS sensor, and performs demosaicing to reconstruct full RGB pixels. Kodak's proprietary color science metadata — white balance coefficients, color correction matrix, and exposure parameters — is applied during the RAW decode stage. The output is written as a 24-bit Windows DIB with bottom-up row order. A DCS Pro 14n file (13.9 MP) produces a BMP of approximately 40 MB uncompressed, while the 14n/c models at similar resolution produce comparable output sizes.
Quality & Performance
BMP applies zero compression, so the format conversion step introduces absolutely no artifacts. The pixel values exactly match the output of the demosaicing algorithm. Kodak's CMOS sensors from this era captured data at 12-14 bit depth, which is mapped to 8-bit per channel in the BMP. The resulting file is a faithful representation of the processed sensor data, preserving every tonal step that the demosaicing algorithm produces from the original Bayer pattern.

Tips for Best Results
- 1BMP files from the 13.9 MP DCS Pro 14n are about 40 MB each — ensure adequate storage before batch converting archived shoots
- 2For general use, convert to PNG instead for lossless quality at roughly one-third the file size
- 3Kodak DCR files from the early 2000s may have degraded storage media — verify source file integrity before conversion
- 4If the target application accepts TIFF, prefer TIFF over BMP for better metadata preservation from the Kodak RAW
- 5Use this conversion specifically when legacy systems mandate uncompressed BMP input format
DCR to BMP conversion bridges Kodak's professional DCS Pro RAW format with legacy systems demanding uncompressed bitmap input. The files are large but universally compatible with industrial, forensic, and legacy Windows applications that cannot decode modern image formats.
