You mean after the problems *you've* discussed using Wratten filters.
I'm not sure anyone agreed with you... I certainly didn't. I don't let
the camera correct anything. It all happens digitally in ACR. Wratten
filters are not required.

I'm going to disagree with you on this point. After the problems we've
discussed about using Wratten filters with digital B&W, I'm convinced
that the unavoidable consequences of the camera "correcting" ambient
colour temperature is problematic. I've resorted to taking the best
possible colour photo, which means correcting with cooling and warming
filters to minimise the camera's interference, then adding the Wratten
filter and converting to B&W in post-processing.
We had a photo here in the last couple of years that consisted of a
winter scene with snow-covered ground. The snow reflected the clear blue
sky, giving the snow cover a bluish hue rather than being dead white.
This could have been corrected with a warming filter.
What filter is over the lens? Why? The only two filters you need
in digital photography are polarizers and ND filters. I don't see a
need for either one here.
