What happens when you convert Kodak RAW to JPEG 2000?

RAW development

Kodak RAW needs camera- and file-aware development to produce a rendered JPEG 2000 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.

Transparency

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.

Encoding mode

JPEG 2000 supports reversible lossless and irreversible lossy coding. A JP2 container, an extended JPX/JPF file and a raw J2K codestream are related but not identical file structures. JPEG 2000 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.

Is Kodak RAW → JPEG 2000 right for you?

Good choice when

  • JPEG 2000 fits your delivery use: Specialised scalable imaging.
  • You need a developed image for a non-RAW application.
  • Your receiving application supports the required JPEG 2000 variant.
  • You can validate the destination’s sample precision and colour interpretation.
  • You need a JPEG 2000-compatible workflow that can hold transparency added in a separate edit.

Probably not when

  • You need the original sensor data and freedom to redevelop it.
  • You need a guaranteed quality or file size before encoder settings exist.
  • You require identical samples without a defined colour and precision policy.
  • You expect automatic background removal or transparency.

Kodak RAW to JPEG 2000 conversion details

RAW development
Kodak RAW needs camera- and file-aware development to produce a rendered JPEG 2000 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.
Transparency
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.
Encoding mode
JPEG 2000 supports reversible lossless and irreversible lossy coding. A JP2 container, an extended JPX/JPF file and a raw J2K codestream are related but not identical file structures. JPEG 2000 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.
Sample precision & colour
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.
Metadata & colour
Format support does not guarantee that an export preserves metadata or colour profiles. Retention and colour handling depend on the future converter; its engine is not implemented yet.
Compression
Kodak RAW: Depends on variant → JPEG 2000: Lossy & lossless Kodak RAW: ExifTool and LibRaw document DCR/KDC recognition and camera support. They do not justify one global bit depth or compression claim across both extensions. Treat the registry group as navigation identity while retaining the actual file type and model for processing. JPEG 2000: JPEG 2000 supports reversible lossless and irreversible lossy coding. A JP2 container, an extended JPX/JPF file and a raw J2K codestream are related but not identical file structures.
Transparency
Kodak RAW: No → JPEG 2000: Yes
Colour depth
Kodak RAW: Camera and recording mode → JPEG 2000: Component-defined precision
Sensor data
Kodak RAW: Raw development required
Dimensions
Pixel dimensions, page geometry, rendering resolution, resizing and orientation need explicit converter policies. The future engine has not defined them yet.
Metadata
Kodak RAW: Capture metadata → JPEG 2000: JP2 boxes, ICC, XML (extensions). Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.

Common questions

Will JPEG 2000 still be an editable camera RAW?

Kodak RAW needs camera- and file-aware development to produce a rendered JPEG 2000 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.

Will the background become transparent?

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.

Which compression mode will JPEG 2000 use?

JPEG 2000 supports reversible lossless and irreversible lossy coding. A JP2 container, an extended JPX/JPF file and a raw J2K codestream are related but not identical file structures. JPEG 2000 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.

Are bit depth and colour values guaranteed to match?

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.

Will metadata and colour profiles be retained?

Kodak RAW: Capture metadata → JPEG 2000: JP2 boxes, ICC, XML (extensions). Which fields are copied, rewritten or omitted will depend on the future engine; retention is not implemented yet.
