Look at it this way... and this is a pretty anal analysis....way beyond practical value probably.... If you had a corner of a building at the very periphery of your first image, the angle along the side of the building would be different than if you turned your camera towards the corner. Therefore different perspective. ( not sure I am defining perspective correctly here, but can not find or know the right word to use...) Another example is near / far relationships and the overlap of the 2. Exapmle ( because word explanations escape me...>) .... Look at an image that has a near object set against a far objective. Look at it head on. Note the amount the near object causes the background to be cut off. Note the location. Now turn your head away., and do the same "measurement".... the part of the background that was overlapped by the foreground object has changed.. and the only thing you did was to rotate. I think a similar problem is skies in panorama shots.... usually the sky changes intensity of color as the pan occurs... ( or even with really WA lenses in the corners.).... Does the sky really have different colors? No. Corrections are used to correct for this... especially true in stitching operations..... Youngsters.. harrumph...... Frank Filippone Red735i at earthlink.net Hi Frank. Is that still the case if I'm rotating on the len's nodal point? Seem not...
