A question about light pollution filters.

[MalcolmD99]

Hi, I am doing some nightime landscape images and am wondering if I use a light pollution filter for the sky will this also cut off ambient light and moonlight on the landscape? Is it possible that light pollutions filters only cut out artificial light?

I want to ask befor I go out and buy a good filter.

Anyone have experience with this issue?

Thanks...

Hi I'm using a 12mm lens on my Sony a7 with an astronomik uhc-E clip in filter. Did some test shots & I'm getting really bad vignetting in the top corners can this be fixed or is this normal.
