Olha só o que achei lendo o datasheet de um sensor.
Do not expose to strong light (sun rays) for long periods, as color filters will be discolored. When high
luminous objects are imaged with the exposure level controlled by the electronic iris, the luminance of the image-plane may become excessive and discoloring of the color filter will possibly be accelerated. In such a case, it is advisable that taking-lens with the automatic-iris and closing of the shutter during the power-off mode should be properly arranged. For continuous using under cruel condition exceeding the normal using condition, consult our company.
Reforça o que eu disse antes, Luz demais queima o filtro RGB.
Será que com o filtro colorido sem cor, melhora a fotográfia em IR ? [
