Looking for Windows command line utility (or .NET lib) to change EXIF information on .JPG files

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?

Should be relatively easy to write a program/script that calls Phil Harvey's amazing ExifTool:

I've used AutoHotkey to call it but your .NET app can certainly call it (any language is fine as long as it can call a command line executable).

Btw, all EXIF tags are listed here:

If you are looking for a utility, then this might suite your needs:

I have no personal experience with them but they support the formats specifies as well as a command-line interface (you could probably contact their support to see if they have an API as well).

I should have mentioned in my first post that ExifTool has read/write support for ORF, CR2, and, of course, JPG. Doc says that it "Runs on all versions of Windows" and I can confirm that it runs on W10/64-bit. Regards, Joe
