Upon wakening up from a freezing night I had decided upon a new valley to try to reach. I got up rather early and began the hike. After a few kilometers I reached another beautiful river and brought out my tripod and ND-filter to try some long exposures.
My conclusion after using the 10 stop ND filter more and more is that it really is overkill in most cases. Sure, if you want to abstract something completely and get an other-wordly effect, then it may be used; if you instead just want to capture some of that movement and add dynamics to a landscape image, than I do think a substantially shorter shutter speed would be more adequate. Since I want everything to be in focus I am forced to use at the veyr least f/8, often leaving me at the max 30 sec shutter speed. I am considering trying a high quality polarizer next time.
As I got higher and higher up in altitude, the wind started picking up more and more. Not to mention the constant drizzling of rain that went up and down in intensity.
