From: Layering contrasting photoselective filters improves the simulation of foliar shade
Digital images of the photoselective filters from LEE Filters, Rosco e-colour + , and Rosco Cinegel used in this research. Multiple strengths of each filter were evaluated including; 0.15–0.90 neutral density (ND), 1/8—full strength color temperature blue (CTB), and 1/4—full strength plus green (PG). Model numbers of each filter are inset in the top-right corner of each filter picture
