4 x 5.650" Glimmerglass Filter Density:4 These diopters are semi-circular piecesGlimmerglass is a line of diffusion filters that produces a soft clean halation around practical and specular light sources, while keeping an apparent sharpness on the overall image. On close ups, the apparent sharpness and fine detail is kept as the effect of the filter lowers contrast while softly rolling into the shadow area. This low contrast affect moderately mutes bright colors. This makes the lower end of the glimmer glass diffusion line
