Aw, man, BestQualityScale and MakerNoteSafety are each specified as 50741.

DNG Spec., page 22:  BestQualityScale Tag 50741 ...
DNG Spec., page 35:  MakerNoteSafety Tag 50741 ...

I looked twice, it's still there.  Which one is correct, and what's the
good value for the other?  I think one or the other is 50739, where
867-5309 is Jenny's phone number.

Would you please put the hexadecimal equivalent next to the decimal tag in
the field description?  That can wait.

Warm regards,

Ross F.
