NRW in het kort
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.
PGM Raw in het kort
PGM Raw
The raw PGM branch reflects the practical evolution of Netpbm-style tool formats: keep the tiny header and easy parsing, but move the pixel raster into a binary form that is much more usable for real data sizes.

Veelgestelde vragen
Why convert NRW to PGM Raw?
Convert to PGM raw when a pipeline needs direct grayscale raster data for vision research, microscopy or scientific-image preprocessing, algorithm tests, or command-line tooling where minimal format overhead matters.
It is particularly useful as an intermediate format between automated processing steps.
What changes when converting NRW to PGM Raw?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to PGM Raw removes camera raw data.
What should I review after converting NRW to PGM Raw?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
