If you are having a problem, please check to see if it has already been fixed in the current version of exiftool (https://exiftool.org/).
And when posting a bug report, please provide the following information:
1) Your system type (Windows XP, Linux, Mac, etc), and your shell if using Windows (CMD or PowerShell).
2) The ExifTool version you are using (the output of the "exiftool -ver" command).
3) The specific command line you are using (or a sample script if having problems with the API).
4) The console output from the command.
5) It is often useful to attach a sample image which exhibits the problem. (Please keep these files small if possible -- I have limited disk space for this forum.) Some users have reported problems uploading images to the forum. If necessary, images may be emailed to me directly (philharvey66 at gmail.com).
Thanks.
