I risk being assassinated, but here goes..
I am hoping some photogs here will post images, taken with a lens before and after gaffering.
Or with a body before and after gafferring.
Or with a flash before and after gafferring.
I am scratching my head, and occasionally my backside when it itches, to the science of a gafferred equipment. Just like the MTF for lenses, the resolution and contrast equivalent for such gafferred lenses is greatly appreciated.
Thanks very much.
