Using Exiftool to bulk rotate astro images (cr2, jpg, etc.)
I got a new Canon T5i and I forgot to switch the setting to never auto-rotate my images. Woops!
It's happen to me in the past and I used Exiftool to rotate all the images in bulk. This works with pretty much any picture format. I was working with Canon RAW files (CR2) and there's not really as easy to do this without using exif tool so I thought I'd make a quick video on how to get that done.

Some tips from u/StarGeekSpaceNerd on Reddit:
-- If you want to just overwrite the original instead of creating a copy, add the the following flag: -overwrite_original
-- To check if file is already horizontal to prevent unnecessary orientation switching:
exiftool -if "$Orientation!~/Horizontal/" -Orientation=Horizontal /path/to/files/
-- If used on Mac/Linux/Windows Powershell, change the double quotes to single quotes.
