Fuji Maker Tags don't work for some Film Simulations (recipes)

[schaeferj]

Dear Phil,

Thanks a lot for the great package. I am using this for many years. Recently, I noticed that for the Fuji MakerNote Tag 0x1401 (MakerNote Film Mode) to indicate the film simulation (recipe) used, does work correctly for Standard Provia Files but not for e.g. Acros. I have attached two files to illustrate:

Exiftool DSC_2021-11-20T16-38-43.jpg shows the Film Mode while the other does not (Please note, that I scaled down the images a lot for email).

Any thoughts?

1) Your system type (Windows XP, Linux, Mac, etc).
Mac

2) The ExifTool version you are using (the output of the "exiftool -ver" command).
12.30

3) The specific command line you are using (or a sample script if having problems with the API).
  I: exiftool -G DSC_2021-11-20T16-38-43.JPG | grep "Film Mode"
  II:exiftool -G DSC_2022-12-17T18-43-58.JPG | grep "Film Mode"
4) The console output from the command.
I: [MakerNotes]    Film Mode                       : F0/Standard (Provia)
II:
5) It is often useful to attach a sample image

If you need to decode the Film Simulation for FujiFilm cameras you need two tags : 0x1401 (that Exiftool calls Film Mode) and 0x1003 (Exiftool calls this Saturation) - the color film simulations are stored in 0x1401 and the black and white/sepia film simulations are stored in 0x1003.

Thank you - this is helpful. It is still strange that 0x1401 is set for F0/Standard (Provia) but *void* for Acros. 0x1003 seems to get 0 fro color and the Filmname for Acros. This is an odd design. Does anybody know whether this is intended usage of meta data by Fuji, I mean where can I find the "official" documentation (if at all)?

Maker note tags are reverse engineered by camera owners since there is no official documentation available (with rare exceptions).

Tx a lot Phil for the great work. This report can be closed then IMHO.

Just to point out - neither of these tags actually have the names of the Film Simulations in the EXIF - they are both numeric and have to be interpreted by the display utility (such as exiftool)

Tx guys for all the quick help again - I implemented it accordingly (with numerical values and look up) in my python scripts and everything works like a charm now - nice community!
