How to do silky waterfall s21ultra

[Nicola10]

Hi, 

Looking for some advice on how to capture a silky waterfall on samsung galaxy s21 ultra. 

Tried yesterday and did not work, I can change the iso level and the shutter speed but this greys out the F stop. Any reason why this happens. 

Any help greatly appreciated.

You need an ND filter to do a longer exposure

Thank you for taking the time to reply. I had thought that might have been the case from doing some research but wanted to make sure I wasn't missing something first.

No prob! I bought a neewer clip on one and also a Gobe 37mm ND1000 which screws onto the same clip.
