I am using Exiftool 8.17 on mac 10.6. and Image files are NEF Software 1.0 Nikon D50
when I use exiftool filename all tags values are return including the below tags. Yet when tags specifically selected values are not returned.
these are the only tags so far I have problem:
WBRGGB Levels
Depth Of Field
Field Of View
using flag -f with these tags also return "-"
