ND filters - are they all the same?

No, they're definitely not the same. Despite the name, Neutral Density filters are introducing coloration into image, more or less. You may find some information here:

Sorry, Polar Pro guys ...

However, criticized Polar Pro filters used in this comparison were made probably sometime around mid 2015. A set of PP Cinema Vivid filters I've purchased recently for my P4P seems to perform much better with manageable image coloration.

Adding onto what Jeff said above, our manufacturing process for our filters has definitely changed since the time that other thread was posted. Our latest filters hold very color neutral, and we are happy to replace any old sets that may be causing trouble. Please email support@polarpro.com if that is the case.
