EXIF and IPTC data

As much of the original EXIF data as possible is written to converted files output as JPEG or TIFF images. For best results it is advisable to keep the THM files which accompany the CRW files. This is because the THM files contain the full EXIF data. If the THM file is not available the EXIF data will be recreated from the CIFF data stored in the CRW file and some data such as the subject distance will not be available.

IPTC data is saved in JPEG and TIFF files when converting all raw files.
