How do I uninstall the camera app I flashed?

[Michael Dvořáček]

Hello everyone,
I've flashed a custom ROM called ressurection remix, and I flashed Gapps including the Google camera app, which I can't uninstall. The problem is that I am trying to install the version with night sight, but when installing it just tries to update the stock Google camera app and fails.
Is there a way I could uninstall it, or just download the night sight on top?
Thanks in advance.

You are rooted, so you can uninstall a system app. If the menu won't let you try Titanium Backup.
