NRW at a glance
NRW
NRW reflects the period when some advanced compact cameras offered raw capture and needed to participate in the same post-processing expectations as larger interchangeable-lens systems.
DDS at a glance
DDS
DDS grew out of Microsoft's graphics API and game-development ecosystem, which is why it feels more like an engine or texture-delivery format than a conventional consumer image file.

It is useful when mipmaps, compression, and engine compatibility matter more than broad image-viewer support.
What changes when converting NRW to DDS?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to DDS removes camera raw data.
What should I review after converting NRW to DDS?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
