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

Posted on 2016-09-30

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
