That is quite an amazing transformation from the original. I have recently adopted the use of a neg scan to see if i can take a print that little bit further. I have to admit though that I have never moved as far away from the original as you have here, though, knowing your skills in the darkroom, I am quite sure that you had this final vision of the print long before you opened the negative up in photoshop.
I used to be quite sceptical of people who posted neg scans in the galleries, but since adopting this way of working I was very supprised to find that there is not anything I can do in photoshop that I can't do, and probably better, in the darkroom (with a printable negative)
Thanks for sharing this beautiful image.
