Problems with viewport orientation and reverse camera view I have been experiencing quite a few problems with the rendered view. As you can see in the video, for some reason the camera view is flipped/reversed and I don't know why it has done this. Like I have the object rotated to the left and in the rendered view its to the right which is confusing. Not only this but whenever I go out of the render view and try to move around the object it rotates around the z axis but flipped on it's side.
I'm also facing problems with the rendered view, I am using a HDRI environment and the spot light I have added doesn't light up my object. Also I want the background to show as black whilst the render is still using the HDRI to light the object but it just appears as a grey background.

If someone could help me that would be amazing! thanks,

Somehow, your camera is showing a negative scale transform.
I would:

Swipe the camera's 'Scale' fields in the Item tab and set to 1.
Readjust the camera using its internal settings (Focal length, or Lock Camera to View,  etc)..

Maybe even swipe the padlocks next to the camera's scale to lock it off. You need special reasons to alter it.
