Hi Gunter,
During the day part, nd filter (10 stops) allows slow speed which reduces the flikering that is a good thing. But when the light fades? you increase the ISO. (100-1600 4 stop)?
The question is, When remove it and what happend after? or what I'm not understand ??
I thought using a vario ND, but you do not recommended in your excelent book for reasons of color shift.
Do you know the filter
Schneider - True-Match Vari-ND
Thank
Hi, in such situation I avoid using an ND filter, even in the daylight part because it can get tricky to remove it without shifting the camera and even trickier to level the resulting color-shift and difference in vignetting afterwards.
ND Filters are a weak measure to really remove flicker. If you consider my tipps for removing flicker when shooting (for example in my EBook) you won't have much issues with flicker anyway - remaining flicker can be dealt with in LRTimelapse.

Gunther, are you saying that in these situations (going from daylight to dusk/evening or the other way) you don't use an ND filter and instead opt for a faster shutter speed to control exposure? (I'm assuming that the lowest iso of 100 is still too high to capture images at 180-degree shutter speeds, and also assuming that you're shooting wide open.)
Thanks...
