Sorry, Dave, too crunchy :-(
No problem - I am trying a few ideas for creating high contrast Black and White's, so it's a bit of an on-giong experiment really, so yes I am sure you are right and I got a bit too carried away. I had also just watched this
Sebastião Salgado video and think I was taken by his 'over crunchy' style and was subconciously trying to mimic it. Which I suppose if that is true, suggests that watching what others do before trying to do what you do, is not always a good idea.
Back to the RAWs for another go then and no harm done I think.
Thanks everyone, always much appreciated
Dave
