As the title already explains I have a shadow in my render without an actual object which casts that shadow. The shadow only shows depending on where my camera is positioned and even when I disable the used lights in my scene. Picture 1 shows how the object should look with the used lighting. Picutre 2 shows the exact same object but I rotated the camera around it. Picture 3 shows how that shadow increases while I rotate further around the object. Picture 4 shows that there clearly is no other object in the way of the light and that camera itself could not cast the shadow on my object.
I think this should solve your problem: Unless there is some special reason you're using "object", "generated" is usually the best texture coordinate to use for procedural textures. Secondly, if you're using a B&W value as a normal map, it should be run through the height input of a bump node first. See below:
