Ken, interesting photo.....Joy
This is a new easy tutorial (written by, Isabel...Retouching Forum).
Add Threshold adjustment layer above duped layer...
Play with slider to get the right amount of BW, this will vary with each image.
On the Threshold layer:
Use a large soft paint brush with black paint to bring back the color.
Flattened image and increased the saturation, if needed.
Last step: Add a Plug-in filter called 'Rough Pastel' set on Sandstone (played with settings there were no instrutions)....this filter is new, to me.
