Strobe Effect?

Frankc · Apr 1, 2016

I flew yesterday in lovely sunshine. However when I looked at my video, shot in 4k, when the camera moved towards the sun, I was flying in a circle at the time, there was a 'strobe' effect on the film.

I assume that was the sun light passing through the blades? Would a petal shade help to stop this?

Thanks

This is about 4 seconds of the clip. It will give you some idea of what I am on about.

Yes and Yes. An ND filter may also help by slowing the shutter speed, but you'd have to use with a lens shade if capturing the sun at an angle. All of this adds weight to the camera.

It already had a filter on it. Will order a petal shade today too. Thanks for the reply.

Just be aware that with the shade on it may hit the ground during the start up gimbal dance.

Very good point! One I had not considered. Perhaps its a fitting job after its had its dance.

Surprises me though buy from China etc 99p buy from UK £5-6+

I had not considered it either until I got one. With drone off and camera hanging the hood touched the table the drone was on.
So I took it off and never used it.

I may try it it next sunny day. But will have to power on drone while in hand. (not the motors)
Then put on the ground for engine start and take off.

I got it cheap from China. But had to wait a month to get it.

Its the blades causing it.
The sun and blades casting a shadow.

Simple fix a lens hood.

I used a small bottle cap that fits over the lens with a little peak on it.

Problem solved.
