The TRUTH about VARIABLE NDs!

You can buy the Freewell K2 at this link at the discounted price of $349 for a limited time http://gopb.co/k2 What was initially just a look at an impressive variable ND system became a video about understanding all the different types and associated problems. I couldn't understand the difference between the K2 and Freewell's previous ones and all the others I had. They wouldn't tell me, so I had to find out for myself! The research and tests I needed to do were endless, as there is so much misinformation and a substantial lack of understanding about them. I hope I have clarified everything here, and it will make you finally understand why your variable ND behaves a certain way. I learned so much making this, and I hope you do too from watching it.
