Raw DTOF curves recorded at 800 nm with SDD = 2 cm, and corresponding to the outmost plots of Fig. 2 and Fig. 4 (i.e. lowest/highest scattering on first/second row and lowest/highest absorption on the first/second column) when using water-clear gel (orange line), turbid gel (green line), body lotion 1 (blue line) and black velvet (black line). To better enlighten the effect of the direct light also the IRF (gray line) is reported in each graph.
