Thanks Phillipe. I have been evaluating ACR 6.2 as implemented in Adobe Photoshop CS5 VS DxO Optics Pro Vs.6.2.0 ELITE over the last two days. This is one of the images that I have been using for the evaluation as it is razor sharp, lots of detail and areas of contrast for noise to get into. This is a B&W Conversion which has made a very special print. The Zeiss Glass just never ceases to amaze me. All this from a single 3.2 second exposure!
Absolutely amazing, Stephen! The B&W suits it so well, though, for the life of me, I would never have imagined doing something like this when looking at this historic engine. Congratulations!
