This time I did the colour and two black and white. The discussion between Manfred and Mike was the stimulus. Not a definitive experiment given the operator's skill set but an intriguing exercise.
The colour was done first, then a monochrome from fresh version and then four hours later a version done from the colour version. The time interval was for two reasons 1) I went out photographing and 2) Intentionally so I would approach the version with no memory of the prior conversion and thus no attempt to replicate. I worked each version until I was very happy with the result. The interesting thing to me is the difference. I cannot be sure this represents technique variant or my changing vision.
