This absorbs almost all of the incoming light, and any remaining light that scatters sideways is absorbed by neighbouring granules. Altogether, the absorption of light is 99.5% efficient, a fact that makes photographing this fish in its natural habitat very difficult.
The subject's unique property absorbs virtually all incoming light, with any scattered light being absorbed by neighboring components. This remarkable efficiency in light absorption, at 99.5%, poses significant challenges for photographing this species in its natural habitat.
