J2K w skrocie
J2K
JPEG 2000 arrived as a major standards effort to improve on classic JPEG, but its practical adoption concentrated in specialist domains rather than in the universal browser-and-camera role held by JPEG.
MEF w skrocie
MEF
Digital photography fragmented into many manufacturer-specific raw formats because camera makers optimized for their own sensors, metadata, and software ecosystems rather than for one shared public raw standard.

Często zadawane pytania
Why convert J2K to MEF?
Convert to MEF when preserving Mamiya camera originals or maintaining compatibility with medium-format photographic workflows that still expect that raw format.
It is appropriate for archive masters and non-destructive editing.
What changes when converting J2K to MEF?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to MEF removes vector scaling. Moving to MEF adds camera raw data.
What should I review after converting J2K to MEF?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
