Camera RAW requires full image development. This browser engine does not implement it yet.
Canon CRW needs camera- and file-aware development to produce a rendered EXR image. White balance, exposure, camera colour interpretation and, where applicable, demosaicing determine that rendering. The destination does not retain the original RAW development latitude. No development settings or camera support are implemented yet.
RAW capture values are not automatically a finished SDR or HDR picture. An HDR-capable destination can hold a developed high-range image, but exposure, camera calibration, colour space and highlight handling determine which captured information reaches it. The future engine defines that development; neither sensor values nor a wider dynamic range are guaranteed to survive.
The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.
EXR supports lossy and lossless codecs. Choose one for the sample types and required precision; .exr alone does not guarantee exact channel preservation. EXR permits different encoding modes or container representations. Its format name alone does not promise lossless output, a quality setting or a size reduction. The future engine must choose a supported codec and sample representation; inspect the target’s compression notes below.

Source and target sample models can differ in precision, channel layout, colour space and transfer function. Lossless compression only preserves the samples actually encoded; a precision reduction or colour conversion can already change them. The future engine defines numeric mapping, orientation and colour conversion; canonical depth facts are listed below where available.
Canon CRW: CIFF → EXR: Typed header attributes, Chromaticities. Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.
