However the photographic evidence is clear.
A "pink" result after exposure to direct sunlight would make a bit of sense. That is, the lens is focussing quite a bit of energy on the chip, and the blue end of the spectrum carries the most energy. A pink result might imply the 'blue' CCD segments have been diminished in sensitivity relative to 'red'. But I agree, a single incident, or a short exposure, most probably will have no effect ... and the effect of longer exposures needs to be studied. How long were the above timelapse exposures? cheerios ... shAf :o) Avalon Peninsula, Newfoundland www.micro-investigations.com =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
