Now, the Lee system holder for the 72mm lens is a clamp on version due to the large diameter of the front element; if you need to rotate the filter, you have to loosen the clamping screw, rotate and retighten. Unfortunately, because the camera was pointing down at an angle approaching 45°, from under the darkcloth, I first felt the holder and glass filter slip from my grasp, heard it slide down the tripod leg and bounce a couple of times.
Of course, you've guessed the end result... somewhere in the depths of the plunge-pool at the bottom of the waterfall, there now resides something like £150-200 worth of Lee filter and holder.
Should anyone else be in the vicinity when the river is less full and should happen across these items, and they are still usable, gizaring
