Comparing original photo to these three, I think the "polarpro" lens filter was causing underexposure and shifting colors towards green. Once you removed the "polarpro", the exposure returned to normal and colors were no longer shifted.
Get your hands on a Color Calibration card (not a white balance) card. Take some drone pictures with and without "polarpro" lens filter of color calibration card in various lightining conditions. Bright clear day, Overcast day, early morning or evening. Then compare pictures with and without filter to the Color Calibration card.
For what it is worth, there is software which will analayze the colors of images taken of the card to actual colors on the card. Even allowing you to make color correction profiles for different lightining conditions, lens, & filters. |
