Nikon D90 makernote support #31

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I'm using metadata-extractor (java app in attachments), but it doesn't get ISO 
Speed from Exif data for my photos taken with Nikon D90.

Expected output:

ISO 100
ISOExpansion    Lo 1.0
ISO2    100
ISOExpansion2   Lo 1.0

Thank you for this report. I'm not in front of the code right now but my guess 
is that the ISO tag wasn't moved correctly when the ExifDirectory was split in 
two. I will re-read the exif spec to ensure that the split is valid and the 
implementation correct.

From looking at line 51 of the exiftool output, you can see that the ISO value 
is actually blank for that imate.  It seems that the D90 doesn't use the 
standard ISO tag, instead using a set of Nikon-specific tags.

It would seem that exiftool has better support for this camera makernote than 
metadata-extractor currently does.

I'm going to update this issue's summary to capture the need to improve 
makernote support for the D90.  Luckily I have one to experiment with.

I can see how it would be valuable to have the standard ISO tag return the 
value from the Nikon makernote, but this is not currently something that would 
be straightforward to achieve.  It's an interesting idea, to try and capture a 
certain type of tag value from across a range of directories.  Unfortunately I 
can't see a straightforward way to add this right now.

I'll update this issue if I learn more about the D90's implementation.
