World-class camera assistant Mako Koiwai recently shot a camera test with two new sets of diffusion filters: Black Glimmerglass from Tiffen and Hollywood Black Magic from Schneider Optics. He compared them to diffusion filter sets that he has in his own collection, which includes Tiffen Soft Effects and Schneider Classic Soft filters.

He’s posted the results here, in full-res glory, although you can preview his work below.
