Unfortunately, this value is not read (to my knowledge) by any of Nikon’s software; and the incompatibilities between Adobe PhotoShop and Nikon EXIF are legion. Thankfully, there’s a neat litle freeware program from Opanda, iExif, that will do the trick.
Install Opanda, and it automatically adds itself to the Windows context menu for JPG files. Right click on the file you want from Windows Explorer, and select ‘View EXIF/GPS/IPTC with iExif’ from the context menu. As the menu implies, not only does the program reveal EXIF data, but any IPTC or GPS tags as well. Very handy for looking at the ‘guts’ of a file.
A helpful reader also informed me of a free on-line tool, Jeffrey’s Exif viewer,which can read EXIF data from images on the web as well as from your computer. I’ve tried it and it’s fairly impressive.
This trick only works for the D70, D2H, and later cameras. (I’ve not tested D1H/D1X/D100, but it does not work with D1 files.) The files must also be straight from the camera — files that have been post processed in Adobe PhotoShop lose this information (along with much of the other EXIF data, sadly). And it doesn’t work with RAW files, which aren’t supported by iExif.
Additional options. Minimalists out there may be interested in ExifTool, a freeware command-line utility. No interface to speak of, but those of you who were undaunted by MS-DOS might find it handy. It is available in both PC and Mac flavors and the Perl source is available as well.
