16-bit linear TIFF ramps and twins (not PQ/HDR10 display masters) for deep-colour loaders, truncation, and tone-map pipelines.
A linear 16-bit greyscale TIFF ramp (0–65535). Not a PQ HDR master — for testing high bit-depth TIFF loaders and 16→8 truncation.
8-bit PNG twin of the linear 16-bit greyscale ramp — compare banding after truncation.
A 16-bit TIFF biased into the upper code values (near clip) — for highlight-rolloff and tone-map tests on linear data.
64×64 linear 16-bit greyscale TIFF with deflate — Wave H depth for high bit-depth loaders.
LZW twin of the Wave H linear 16-bit greyscale TIFF.
64×64 linear 16-bit checkerboard TIFF for bit-depth and downsample tests.
Linear 16-bit TIFF with a dark edge and near-clip field — tone-map edge case.
