If I don't have a tripod I just lay my camera on a rock or whatever to keep it still......The shots above were shot that way.
i spoke to a lot of experienced photographers on line last night about water shots,and they seemed pretty well split down the middle on this subject,of soft water you either like it or you dont ,but all seemed to be in agreement that you cant see water like this anywhere in the world,but only on a photograph
When you see waterfalls, they are moving. If you just "snap" a pic of it, it doesn't capture the movement but Stops the water in motion. Shooting with a long exposure gives back some movement and projects that through the picture to make you "feel" like you were there. When it's done right it is beautiful........
(I am the half of experienced photographers that seem to like it!)
