Preview Render Backwards

Hi, I’m just starting out w/ Blender and I’ve run into a frustrating problem.
I had been tweaking my model’s texture and at some point every time I render/preview the resulting render is facing the opposite (180 degrees) direction. Hopefully there is some very simple fix.

Need a bit more information, but have you tried flipping the normals of the mesh?

go into edit mode, select everything and press CTRL+N

if your whole scene is backwards, then i have no idea, could you post a .blend?
