MEF at a glance
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.
MD at a glance
MD
Convert to Markdown when the output should remain easy to edit in plain text, store in Git, review in diffs, or feed into automated publishing systems.
It is ideal for documentation, articles, developer guides, release notes, and notes that will later be rendered into richer formats.
Use Markdown when semantic structure matters more than exact page layout.
