描述

The older CRW file format (superseded by CR2) is treated as a TIFF file, however it does not meet the library's expectations of TIFF files.

When TiffMetadataReader attempts to verify them, it falls over with ExifReader expecting 49492a but getting 49491a due to the difference in file format.

CRW data is stored as CIFF (Camera Image File Format) which is similar to TIFF, but differs.
