Hi: Looking at the Exif of my photos I can't find the values used when the flash fires. I would like to see if I used TTL, TTL BL, etc and if I used any flash compensation. Is there any program I can use to see what I want? Thanks in advance.
This information should be buried in the 'MakerNote' section of the EXIF data. You will need an unedited version of the image, as many editors strip this section of the EXIF from the image. And then you can use a program like ExifTool by Phil Harvey and maybe an additional resource that can provide a GUI interface. There are versions of this program form Windows, Macintosh, and UNIX/LINUX.
The information will be under the 'Nikon FlashInfo0103 Tags' on Nikon Tags
