My Olympus camera produces images with EXIF tags "Subject" and "Title" set to "OLYMPUS DIGITAL CAMERA".
I want to be able to change these using a command line utility that I can call from an application I have written that manages certain aspects of my photo collection. Since my application is written in .NET, I'd also be willing to look at using a third-party library that would allow me to change EXIF tags.
I deal with OLYMPUS .ORF files, Canon .CR2 files and of course, .JPG on Windows 10.
Is there an obvious choice as to what tool I should use? I subscribe to Adobe Creative Cloud. Perhaps they have a tool that I could use?
