GoPro Lens Hood

I do aerial photography for the company I work for using a DJI Phantom w/ a GoPro Hero 3 mounted to a Zenmuse gimbal. The setup works nicely but I've had some problems with "scanlines" showing up during specific flying conditions. These lines appear when the propellers are just on the edge of the frame, and when the sun is in view. When this happens, horizontal lines are created that ruin the shot. Talking to my director about the issue, he said a Lens Hood might solve the problem. While his suggestion was good, no one makes a Lens Hood for a GoPro.

There are several hats I wear, and Multirotor/Drone Pilot is only one of them. Since I also do 3D CAD work and have access to a 3D printer, I decided to make my own.

After some trial and error this is what I have come up with:

While our printer resolution is somewhat large by todays standards, it gets the job done. I can film in both Wide and Medium shot angles without seeing the edges of the hood. The hood performs as promised, eliminating the scannlines. However, because it increases the frontal area of the camera, and is basically attaching a small sail directly to the lens, some Jello works it's way back into things. So there is a bit of a trade off. It's a good thing I made it press-fit so I could easily remove it as needed.

If you'd like your own, it's available at Shapeways here

UPDATE:

Still working as advertised but I'd add an additional word of caution: If you are flying in higer wind conditions be aware that the sail effect on the camera may overpower your gimbal.
