I tested out the Sandmarc ND PL Filters on the Mavic Air to see how I can pull off the best looking picture possible using Premier Pro to colour grade. I filmed all these shots using ND8. Overall I think Sandmarc filters are great value for money. Especially if you’re looking for a cheaper alternative to the Polar Pro. Very happy with my purchase!
On a side note also, Sandmarc customer service is first class. One of my ND’s was cracked when I received the first set of filters. I told them the situation via email and I got a new set sent out immediately!
