ARW at a glance
ARW
Convert to ARW when preserving Sony camera originals or returning processed material to a Sony raw workflow.
It is useful for archival retention, high-latitude editing, and non-destructive photographic post-processing.
RST at a glance
RST
Convert to RST when the content is headed into Sphinx or another documentation system that benefits from directive-rich plain text.
It is well suited to API docs, developer manuals, internal technical references, and documentation that needs cross-references, notes, code blocks, and publish-time transformations.
Use it when documentation semantics are more important than office-style page layout.
