Two general models for simulating different types of foliar shade. In all panels, black lines in SPDs represent either moderate or deep foliar shade, and colored lines represent the SPD from the designated filter(s). Red bars indicate 400 and 700 nm, respectively, designating photosynthetically active radiation (PAR) between the red bars. A An area of moderate foliar shade with more diffuse light has an SPD with a (1) relatively high B:G ratio and a reduced R:FR ratio. A single Rosco Cinegel 1/4 CTB filter (2) simulates the B:G ratio of the SPD from the moderate foliar shade site, but does not simulate other parameters well. A single Rosco e-colour + 0.30 ND filter (3) similarly does not accurately simulate the moderate foliar shade SPD. The combination of the 1/4 CTB and the 0.30 ND filters (4) accurately simulates the entire moderate foliar shade SPD. B An area of deep foliar shade with a (1) relatively low B:G ratio and a much lower R:FR ratio. A single Rosco e-colour + 1/2 PG filter (2) does not simulate the deep shade foliar shade SPD. The combination of Rosco e-colour + 1/2 PG and a Rosco Cinegel 1/4 CTB filters (3) still does not provide an accurate deep foliar shade simulate. The combination of the PG, CTB, and a Rosco e-colour + 0.60 ND filter (4) accurately simulates the entire moderate deep shade SPD
