Care to comment on it's usefulness if one is trying to teach the eye to see in B&W values. Ansel Adams suggested using this filter for newbies in B&W photography. B&H sells one by Peak for $50." I have used such a filter produced by Zone VI and currently marketed by Calumet. It is quite useful for judging tonal separations -- for example, buildings against the sky and the like.
