Here is the first shot i managed, managed a decent water trail shooting at f18 13 seconds exposure, using cokin poloriser and a 2 stop full nd filter.
i then shot down the gorge using 70-300 is, 6 secs at f7.3 @300mm. love the mistiness of the water!
and another 6 secs at f18 @220 mm
Changing to another position on the rocks, shooting with 100mm L macro
15 secs at f5.3
Then i tried another few water trails shots with 17-40L
this one 10 seconds at f18 @23mm
6 seconds at f18 @ 23 mm
Turning around to shoot downstream across the waterfall
And a four frame focus stack to increase depth of field, 15 seconds at f22 @40mm
all shot with canon 5d2, 100mmLmacro,70-300 is & 17-40 L
