Flash for digitized film photos

[Masa]

I have thousands digitized old film photos in TIFF format.
Some of those photos are taken with flash and some photos are not taken with flash.
Which kind of command I should use to mark those photos which are taken with flash?

I tried "exiftool -flash=fired" and it now looks like this:

Code Select Expand

Flash Fired                     : True
Flash Function                  : False
Flash Mode                      : Unknown
Flash Red Eye Mode              : False
Flash Return                    : No return detection
If I add flash settings with Windows Explorer it only looks like this:

Code Select Expand

Flash                           : Firedor

Code Select Expand

Flash                           : No Flash
It looks simplier if I add flash with Windows Explorer.

Try extracting with the -a -G1 options to see where this information is stored.  You can write exactly what you want with ExifTool, but sometimes you need to be a bit more specific and specify the group name.

Thanks!

I tried "exiftool -flash=fired" and it now looks like this:

Code Select Expand

[XMP-exif]      Flash Fired                     : True
[XMP-exif]      Flash Function                  : False
[XMP-exif]      Flash Mode                      : Unknown
[XMP-exif]      Flash Red Eye Mode              : False
[XMP-exif]      Flash Return                    : No return detection
And when I add the flash with Windows explorer it looks like this:

Code Select Expand

[ExifIFD]       Exif Version                    : 0231
[ExifIFD]       Flash                           : Fired
[ExifIFD]       Padding                         : (Binary data 2060 bytes, use -b option to extract)
So correct command for simple flash field would be "exiftool -exifIFD:flash=fired" or "exiftool -exifIFD:flash="no flash""

So correct command for simple flash field would be "exiftool -exifIFD:flash=fired" or "exiftool -exifIFD:flash="no flash""

I would suggest simply
exiftool -EXIF:Flash=Fired /path/to/files/

The EXIF:Flash tag has a list of possible values to set.  See here.  You would set it to the words on the right, with quotes if there is a space in the value.

Setting just -Flash=Fired is using the Composite:Flash tag, which sets multiple values in the XMP group.  See the Composite tags page for the list.
