Propeller shadows on video

[Roger]

Any suggestions on the best way to shade a GoPro Black on my DJI Phantom? Anyone using a shade of some sort and if so could you please describe how.
Thanks.

Thanks for that quick reply. I have tried a thin piece of cardboard around the lens but have found that it needs to extend very far out so as not to catch that prop flicker. I'm guessing that any type of cover will help but not eliminate the problem depending on the angle of the sun. Am I right on this? Thanks again.
