my reference photo has a weird rotation I am completely new to blender. I am following Blender Guru's instruction too create a 3d coffee mag. However, when I add a reference photo, it has been rotated automatically. I am pretty sure that I have never changed the coordinate. Why would this happen? What can I do to fix the problem?
You probably weren't in a front view when you imported your image, so select it and press AltR to reset its rotation. S to scale it, G to move it.
