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.
