If the Nikon camera is not used in a drawer for a month or two in humid weather, why does the recent photo turn purple?

- -, Don’t you know that cameras are afraid of moisture? Purple? That should be a lens problem! Mold that grows in humid environments is the most harmful enemy to camera equipment. This is because the surface of the lens is coated, which provides rich nutrients for the growth and reproduction of mold. The mold decomposes the components of the film on the surface of the lens, producing dot-like or filamentous mold spots, thereby affecting the light transmittance of the lens. And imaging, severe cases can lead to lens scrapping, so mold is the biggest killer of camera equipment.
