I think that the highlights have been lost though. There are some patches which are clipped already but after the adjustment much more of the snow has been lost.I tried again with just from the waterline upwards selected and used a mask to colour balance the highlights only. That clipped the highlights in the top area and not the bottom but that's hardly an improvement. I tried graduated changes using Raw tools and an adjustment brush in Ps. None of these loked natural. I think that Philippe's simpler global adjustment is much more effective than any thing I tried. Well done, Philippe. I should have said at the beginning too, it is a lovely shot by Spencer and well worth some extra effort. 2010/1/12 philippe.amard <philippe.amard at sfr.fr> > I just tried this > Magenta adjustment only (saturation down 99), in LR > > > http://gallery.leica-users.org/v/Phileica/Playground/ICe-LR-Magenta+saturation+minus+99.jpg.html > > > > Best > Philippe > > > Le 12 janv. 10 ? 08:11, Pasvorn Boonmark a ?crit : > > > >> Hi Spencer, >> >> Wow, this is a tough one. >> >> Original - <http://www.aotera.org/tmp/ice.jpg> >> With my adjustment - >> <http://farm5.static.flickr.com/4037/4267753913_c31ba96125_b.jpg> >> >> This is what I did: >> a) duplicate layer >> b) desaturate RED, and Magenta >> c) Overlay the top layer and adjust opacity >> >> The top part looks more B&W.
