@Julian de'Courcy,...you needn't spend any time looking up that chat between myself and
@Pete Askew. It was merely a question from Pete to me as to whether I had ever scanned a B&W neg as a color neg. That got me scanning my last couple of rolls of B&W as color negs. (I told the scanner to use 48 bit color.) The tone that produces can be pleasing. That's all there was to it really.
