in case you have difficulties to find the bluebells: better click on the image and see it large! trying to find the best compromise between sharp water droplets and the impression of fast moving water i did a small series with different exposure times, and 1/100s gave the best result. this was a bit astonishing for me as i had expected the best effect at slower speeds of maybe 1/30s, i guess this is due to the the big amount of water coming down the mountains after the rainfalls.
the raw file was converted with the bibble5 preview 2 version, and despite some flaws, the region tool and selective color tool can give already great results. without it, the bluebells would be almost invisible in the small image size.
Yes, you're right. Works nicely in a big picture, but it's somewhat problematic in the smaller frame.
So, print it big!
