Using the ‘HI’ ISO setting on my D200 results in the ISO value being missing from EXIF as it somehow is not properly ISO 3200 but instead some equivalent. I still want it known from EXIF data that my goal was ISO 3200.

I got some Windows tool named Reveal (albumshaper.sf.net) but I don’t totally thrilled. Works. But not elegant. This piece of software uses an EXIF toolkit from http://www.exiv2.org/ named Exiv2. All open source and everything. I got it. Compiled it… Installed it.

There is a neat tool for fixing Nikon ISO values. I like that. But it might not always apply to what I am doing. Took a bit to figure out how to set ISO.

exiv2 -M”set Exif.Photo.ISOSpeedRatings <value>” mo <filename>

where -M is to indicate the next string enclosed in ” ” is the command

where mo is the command to modify exif data
