Linear Polarizing filter ?

[nwcove]

Anyone using a linear polarizing filter? If so , are there any adjustments that should be made in the camera settings.....or will auto work ok for general use ? ( p3s)

Auto will work fine, light metering will account for the reduction in light. I would go for a circular polariser in preference though, not as critical in this application as it might be with DSLR (metering can be effected where the light sensor is after the partial mirror in an SLR) however the circular filters tend to have better coatings on the back.

You need to rotate the filer for optimum effect prior to launch.

You shouldn't have to make any changes to the camera settings. Just make sure you have the filter turned the right way to filter out the polarized light that you want to filter out.

Thanks WTB, i bought a set of filters ...impulse buy......that has three nd filters and the linear filter.
rotate the filter ? i may be in over my head with this filter deal . lol

Yea. Polarizes are usually used insitu when they are adjusted for the offending glare. Not sure what benefit they are when fixed and inaccessible at time of exposure.
Let us know!

A linear polarizer is a filter which selectively allows the passage of only certain orientations of plane polarized light. At one orientation it might allow the passage of only vertically polarized light, while if rotated by 90 degrees it would allow the passage of only horizontally polarized light. If you set it half way in between, the filter would allow passage of only 45 degree plane polarized light. You'll have to rotate the filter with the camera feed coming through the DJI Go app to see where you want to set the orientation of the filter rotation. The affects of the filter will be most pronounced when looking at bodies of water and at the sky.

If you have polarized sunglasses, go outside with them. Hold them away from you face and rotate them. You'll see the light coming through the lens change as you rate them.

A circular polarizer is a linear polarizer with an additional layer bonded to it. They were designed for SLR cameras. The light would bounce through mirrors (and/or prisms) and this would affect the polarized light enough to affect the in camera metering. This isn't an issue with the camera on the Phantoms.

and thanks anotherlab.......i guess trial and error is in my future ! my usual take off spot has much different lighting than where the bird ends up filming/taking pics.
