Okay - here comes what might be a stupd question. Is it the filter that makes for that gorgeous silky water or is that just you setting the camera to long exposure?
@lily Not a stupid question at all!! The long exposure creates the silky water, but I did use the filter, because I could then do the long exposure in the middle of the day. With the lens open so long, the filter is necessary to block out the light. Hope that helps! Thanks for asking!
@pawar_ramesh Thank you Ramesh!
