When Should You Use IIQ vs CR2?

IIQ vs CR2: Key Differences

• •IIQ and CR2 diverge on compression: lossless compression for the source, lossless compression for the target.
• •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
• •Alpha channel support: CR2 lacks transparency support.
• •IIQ files are typically 50-150MB per image from medium-format backs while CR2 files range 20-50MB per photo depending on camera
• •Use case fit: IIQ targets professional studio photography, digital back capture and CR2 targets canon photography, professional raw editing — your choice depends on which workflow stage you are serving.

Troubleshooting IIQ to CR2 Conversion

• !CR2 shows visible compression artifacts → lower the compression level or switch to a lossless variant
• !The converted CR2 image looks washed out → the source IIQ likely uses a wider color space than CR2 supports
• !CR2 file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
• !Text in the converted CR2 looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
