CR2 at a glance
CR2
CR2 became the dominant Canon raw family through the long DSLR era, so huge real-world photo archives still depend on stable CR2 decoding and migration paths.
L16 at a glance
L16
The slug appears in product data with Light-camera lineage, but public documentation is sparse enough that the safer interpretation is a specialist raw grayscale interchange usage rather than a fully published neutral format family.
