Thanks a lot to all...
regarding the time exposure, Peter, fully agree with you, I'm hiding away from silky effect also, but this time I imagine this shot, not as a merely waterfall reproduction, but as a moment of light, not necessarily having to do with water.
Sorry for my english.
Kevin, this location is, also actually my second home, I'm traveling Laugar (10 kms away from Godafoss) once every two months for work
so, sometimes you get a calm time there to think about a different shot, away from the common tourists rush... and sometimes you can also be so lucky to find moments as shown in the next post...
