I'm a huge fan of O. Winston Link.
His photographs were both technically challenging and well composed in a way that draws me in and lets me spend hours looking at one, and by and large are around a subject of great interest to me(rail photography, or more specifically the last days of steam power on the N&W railroad). It doesn't hurt that his rail photos were in/around the Shenandoah Valley, New River Gorge, and other Va, WVa, and NC mountain locations.
All and all just an incredible photographer, although one who had a quiet but sad last decade of life quite literally locked in his darkroom by his much younger wife who wanted him to keep turning out prints for money reasons.
I'd love to own an original O.W. Link print, but for the latter reason I have some ethical hang-ups about ever owning one of his late prints even if, IMO, they were some of his best after years of basically perfecting printing some of his most well known negatives.
