Lately I have been playing around with my new-ish (I haven't used it much, even though I have owned it for months) 10-stop ND filter. This thing is actually pretty nice. No color cast. Doesn't seem to affect sharpness much (as long as I remember to turn off lens image stabilization). Overall, I'm happy. https://www.amazon.com/gp/product/B00GMXD9E8
This is lake Mendota on a morning that started out very cloudy, when I got to this spot the clouds were almost gone, and then became super cloudy again a half hour later.
I kind of wish there were more clouds here moving through, but oh well.
