Hey guys. Wondering if anyone else has experimented with ND filters. Probably less of an issue with GoPro but the Mobius has issues adjusting to direct light. Tends to darken the contrast. I modded a plastic soda cap to fit the wide angle Mobius lens and screwed in the ND4 filter. Helps a lot with the light contrast adjustments but it also adds a blue/purple hue. My understanding from reading photography sites is that this is common for ND filters. For photography it's not a huge issue because they adjust in post production, but I'm hoping I can adjust the Mobius settings for good results without lots of post production editing. Anyone have experience with this and have any suggestions? Here's the footage of my 1st test run with the ND filter attached. This was taken around 5:45 in AZ a bit before sunset.
