Interest was such that Gary has made a pdf of his presentation for members to download, should they wish to do so.
It is only a tad over 2mb in size so won’t take long to download nor use much bandwidth.
You can find it here
Gary referenced a video by Gavin Hoey in his presentation that you can view here
Gavin Hoey also has a related video here that deals with photographing waterfalls and one here that teaches you about how to get silky smooth water.
