Thanks for the tips.....yeah, anyone can feel free to DL and fiddle, although they are jpegs.....I have the original RAWs as that is how they were shot.
For these I used Sigma pp 3.2 Mac, although the screen I am using is so poor that I could not really look at the photos in the proper way. The day was largely overcast, although some sun was out early and then none later. When I get home I will throw a couple RAW files up and give the URL if anyone wants to fiddle.
I didn't do much in SPP, because I don't know how to use it yet. For instance, it seems to start processing the photos as soon as I open it.....rather than waiting for me to make an actual command.
