I want to know the answer to the following question:
In what year was CIPA DC-004 introduced?
All the background I'm provided with is that "Because the 1998 version of ISO 12232 did not permit measurement of camera output that had lossy compression, it was not possible to correctly apply any of those measurements to cameras that did not produce sRGB files in an uncompressed format such as TIFF.". Is that enough to answer the question?
Answer: no
