Aloha,
looking a Paul's images from Arkansas; I'm reminded of how incredible the improvement to the dynamic range of digital cameras has gotten over the years.
I don't know how much the shadows are opened up in post, not that its an issue, it would be interesting to know if the shadows were deeper, then opened in post.
I started shooting digital with a canon ids mark 2, even then you could open the images up a good bit in post but, you could tell.
Anyway Arkansas; who knew! nice location, nice shots!
