I like it Jase but I think you need to go 1) wider or 2) vertical 3) stitched pano as I'm left wanting to see more. Very good control of the water
Man thats sick. What settings were they one. Im looking at doing a lot more slow shutter speed for year 12 but mine never turn out right. Always over exposed.
Anything over a few seconds should create sufficient 'blur' in the water. The problem is however actually getting your shutter down that low in broad daylight as you are physically limited by how far you can stop down your aperture/drop your ISO which is where it sounds like you're going wrong.
If you have your ISO as low as you can, and your aperture closed to f/22 or smaller and you're not getting a shutter speed low enough to create blur, then you want to be looking at acquiring a set of ND filters (essentially dark glass that cover your lens and reduce the amount of light entering). Shooting on overcast days also helps as you don't have as much glare (especially from water on foliage) and will mean there is less light available.
Lastly, positioning and composition. It's easy to shoot a moving stream and it's likely that someone has done it before you anyways. Get yourself a good tripod and actually get
in to the stream for a completely different perspective - something that's different and actually screams 'wow'! I've been photographing a few streams lately and had my camera barely inches off the water and it really does make the differences (note: invest in a
good solid tripod before you attempt this).
Some of the best times to photograph waterfalls is actually in the rain so keep that one in mind.
