Accurate to within 1/3 stop, no perceptible color shift
Tested exposures of various scenes with and without this filter. Nikon Z6 on aperture priority chose 1/40 sec (f8, ISO100) for the scene without the filter, and 25 seconds with filter in place - a 10-stop difference. The two images look identical in LR in terms of exposure. A very slight increase in saturation for the longer (filter in place) image but no perceptible color shift. Very happy with this filter.
