Camera issue

dimedrol · Oct 4, 2015

guys, do you think I should return my Phantom 3 Advanced to the seller basing on the below video?

I am shooting in full hd, 50 fps. This effect presents in approximately 15% of my videos

Those are shadows from the sun shining through your props. You can work around that by installing a lens hood, install a lens filter, flying in a different direction, or flying at a different time of day (e.g. when the sun is not high in the sky).

Can someone show similar video if that's a common problem please? That would be a big relief.

Thanks

Your camera is working as designed. Got any lens filters? That's usually an easy way to fix the problem -- and, it'll allow you to shoot higher quality video.

I found it looks exactly like mine. Thats good to know!

How do lens filters prevent prop shadows from falling on the lens? Isn't it a lens hood that I need to prevent that?

A lens hood will help prevent the light from hitting the lens. I'm sure there are certain angles where it wouldn't entirely fix the problem though. A lens filter allows you to slow down the shutter speed -- which can eliminate this problem and/or make it much less noticeable.

Lens hood prevents some portion of the light from hitting the lens - true. It doesn't stop shadows from hitting the lens though. Thanks for quick response and help!

I don't know the science behind it. But, I do know people only use lens hoods to prevent/minimize prop shadows.

I don't think you convinced him.
