Hello!

I am not at all knowledgeable in programming, but I am desperately searching for a way to change a creation date (the original date of the photo according to the camera) of an image. Searching for software that does this, I came upon ExifTool and thought I could give it a shot at the terminal (which I have used before twice in my life). After a few hours, I realize I cannot get a hang of it. 

Could anyone give me a patient hand here?

Thanks in advance.

You give me nothing to go by.  I don't even know what system you are running.  Did you see this thread?: https://exiftool.org/forum/index.php/topic,4888.0.html

Ok Phil, thanks so much.
I was unsure if I would get a reply at all.

I am on an old mac with OS 10.6.8.
The cámara is a cannon rebel xti.

What do you need?
Em...
The photos are wrongly dated, as if they were from 2012. They should be 2014.
Because of this unexpected error, I cannot use them for what I took them for.

Am I being silly stupid if I just ask for what to write on the terminal in order to change that?

Thanks so much Phil

To change the time by two years, try this command in the Terminal:

exiftool -alldates+="0002:00:00 00:00:00" DIR

(instead of typing the directory name, you can drag and drop the folder onto the Terminal window)
