This can't be done in a conventional digital camera, because the sensor doesn't know what the original wavelengths were.
但鲨鱼缺少圆状细胞，这种细胞可以对不同波长的光线分别作出反应。
Yet the sharks lacked cone cells, which respond individually to light at specific wavelengths.
光线的波长——即是对应着其颜色——取决于该微粒的尺寸。
The wavelength, and hence the colour, of this light depends on the size of the dot.
较低的一层俘获通过上层的未经干扰的波长较长的光线，也能吸收顶层重新放射和侥幸逃脱的低能量的光。
The lower one captures longer wavelengths that have passed unperturbed through the upper, and also any lower-energy light that has been re-emitted within the top layer and somehow escaped.
