Fig 2 is incorrect. Specifically, Fig 2A, which depicts the different geometric configurations discussed in the article, plots the axis defining the parameter h_r in reverse and shows the examples of the two extreme “film positions” (marked as h_r = 0 and h_r = 1 in panel (A)) in the opposite order. The authors have provided a corrected version here.

As a result, in the third paragraph of the subsection “Spatial arrangement of melanin affects shielding effectiveness” in the “Results”, the phrase reading “We repeated the simulations for the aforementioned values of ρ_A for two configurations: melanin ghosts and film with h_r = 0.” should be corrected to “We repeated the simulations for the aforementioned values of ρ_A for two configurations: melanin ghosts and film with h_r = 1.”.
