Hey Jani,
Those smooth turns of yours are making me want to try Litchi
Well done hehe
I would suggest getting a few nd filter,
The one i use the most is the 32 nd filter for bright days
So you can keep the shutter speed low and not be too blown out
Here is my latest video with the polarpro 32 ND and polarized (less glare in the water
I know, i have phantomfilters.com filters but i don'n use them because so hard to change, maybe i install ND4 and keep it all the time inside the camera.
Maybe better than nothing.
