Are there any that show DR, HR or SN modes? I used the EXIF reader from RawDigger, which dioesn't show that info.

DR is written to a field called "Development Dynamic Range", it's shown in RawDigger, too. When AUTO DR is used this field is split in two fields of different name, as far as I remember (would have to search a DR file to get the correct tag names).

At DR 100 both HR and SN use the very same raw data, they are just developed differently by the camera or raw software. Once there must have existed a "EXR Mode" EXIF tag, but for the X10 the only difference in EXIF I could find is that HR is labeled "RAW Version" 102, while SN is labeled version 103.

Unfortunately this tag is write-protected, else one could try to change its value to see the outcome.
