Photoshop VS LightRoom

Hi all

I’m a bit out of the loop. Is there anything you can do with Light Room that you can’t do with Photoshop? If you have photoshop, how can light room still be usefull?

It’s a great file manager for pictures and every operation in non destructive.
For processing raw images there is no better app. For renders I’m not sure if it can be useful.
It’s a photo app.

Thanks, I need to learn all this photographic stuff it seems
