Sorry, but I just don't see how that's possible. The angle of view does not change, regardless of the position of light sources or what you're shooting. By design, the lens hood does not impinge upon the area of the image circle which is sampled by the image sensor. Depending on lighting, you could be seeing a shadow from the hood that is cast upon the lens - that's the lens hood doing it's job. But if you are using the correct hood, and it is properly mounted, you will never see the lens hood in the image.
