After much experimenting in Lr Cc and Ps Cc I finally decided on the treatment I would give this year's Saltaire Inspired exhibitors images.
In the end I didn't use Ps to process any of the images, it was all done in Lr. I'm finding that increasingly Ps is getting used less and less for post processing as I can do everything I want in Lr CC.
If I need to add text or logos to images then Ps is the only option, and also if i decide the image requires a lot of use of the content aware re-touching, iI find its quicker in Ps.
Here is a selection from the final images, all taken on Canon 5D2 with either a Canon 16-35mm f2.8 L II, 24-70 f2.8 L or 70-200mm f2.8 IS L.
