Rosco's R119, their most popular theatrical diffusion, is recommended for shorter throw distances when a gentle diffusion is desired or medium to long throws when a heavier effect is desired. Its softened beam edge maintains definition with a gentler gradient, making it excellent for blending washes like front or side light. Light Hamburg Frost provides a little extra blending power when spacing is a touch further apart. Lighter than R114, it's additionally recommended for follow spots and slight diffuse focus for ellipsoidals.
