Optimize your conversion workflow with technical recommendations.
Prepare RAW Decoding
- Demosaic CR2 before scaling to preserve luminance detail when mapping to PGM
- Apply white balance to CR2 sensor data to avoid neutral bias in PGM output
- Use camera-specific matrices or test patches to adjust color-to-gray conversion coefficients
- If CR2 uses lossless compression, decompress first to avoid additional quantization artifacts
- Record CR2 shutter and ISO in a sidecar to track noise characteristics post-conversion
Plan Archival Strategy
- Store original CR2 alongside PGM exports to retain full raw sensor data for future edits
- Use sidecar XMP files for EXIF and maker notes since PGM cannot carry them
- Prefer 16-bit PGM when CR2 has 12/14-bit captures to reduce quantization loss
- Compress archived PGMs in ZIP or TAR.GZ for storage efficiency without altering pixels
- Tag archived sets with camera model and lens data extracted from CR2 metadata
Verify Output Quality
- Compare histograms between CR2 processed luminance and PGM to detect clipping or lost highlights
- Check for banding at 8-bit PGM and switch to 16-bit if gradients degrade
- Validate that demosaiced edges in PGM match expected detail from the CR2 RAW
- Use test charts to confirm tonal mapping when converting proprietary CR2 color matrices
- Open PGM in ImageMagick or GIMP to confirm numeric pixel ranges and mean luminance
Performance & Privacy
- Process CR2 batches locally to keep sensor images off external servers for privacy
- Group CR2 conversions into 20-50 file batches to balance memory and throughput
- Close other memory-heavy apps to avoid browser OOM during large CR2 demosaic steps
- Download and archive PGMs promptly; browser tab suspension can interrupt processing
- If network is unreliable, export PGMs to local disk rather than cloud storage during conversion
Fast Processing
Close unused tabs for maximum throughput.
Client-Side Privacy
No media leaves your device.
Broad Compatibility
Output files work across all operating systems.
Pro Tip
For batch conversions, process in groups of 20-50 files to optimize memory usage and avoid browser slowdowns.
