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.
