EXIF tool with CMD and GUI not doing anything

[erikbaldwinson]

Trying to use EXIF tool to change both black and white level on .DNGS in windows with both CMD and GUI.

The command I'm using in CMD is "exiftool -BlackLevel=0 <file_name or *>.dng"

I've tried various entries and in GUI I've entered "exiftool -BlackLevel=0" multiple times and nothing changes or updates.

It will allow me in GUI to manually change each file in the workspace though... not a solution for thousands of .dngs needing white and black levels changed.

Thx for any of your ideas/support/time

I'm not sure, but using the "ExifTool direct" feature, I think you would do this by entering "-blacklevel=0" for the command arguments (ie. don't put "exiftool" in the command)
