Macroscopic photographs of a single flake of a polydomain CNC film [R = 100 μmol/g, H = 0, cf. Fig. 14(a)]. Reflection in (a-c) specular and (d-f) off-specular conditions using either (a,d) no polarizing filter, (b,e) a Left-Circularly Polarization (LCP) filter and (c,f) a Right-Circularly Polarization (RCP) filter (scale bar 1 cm). The polarization of the reflected light by the cholesteric structure is LCP in specular conditions, whereas in off-specular both polarization states are present.
