A few days ago, I posted an image where the water was just about to go over the falls.
Ste Anne's Falls
I've now PP'ed a view downstream of the top of the falls. The volume of water, due to the spring runoff is quite impressive. I did a fair bit of bracketing of shutter speed, trying to get the water too look right; not too much blurring and not too frozen. This one I shot with the D800, rather than the GX7.
The challange was trying to find something that works overall (a bit like working with mixed lighting) and different flow rates work better at different shutter speeds, so one has to use the "best" compromise. This is a large format image, so you might find it interesting to view in Lytebox to see what I mean here.
