Sounds like you're looking for a freecam/photomode mod or something similar, where you can move the camera around freely, right? Reshade, being generic in nature, can't access game information outside of what's on screen, and as such can't manipulate things in world-space, like lighting and camera movement.
Free cameras for games can be found with a simple "[game] free cam" search, if not our forum's very own OtisInf has a
framework
you can use to build free cameras for yourself. There's quite a few already built and ready to go.
