I have only 2 for sale (11x14 & 16X20, both TechPan negs),
Exposed Roots, Lodgepole Pine
El Capitan Reflection,
out of a couple hundred MF and LF mixed that I actually consider for sale as fine prints – because a good print is a good print, no matter the format.
Regarding Rowell, those large 35mm prints, though fantastic images, are mostly hybrid digital prints. In the few optically enlarged still on display, you can see individual dye clouds (i.e., color "grain") from across the room. They are not fine art prints, and I don't believe Galen ever claimed that they were. I've never talked with anyone who didn't think this degree of digital enlargement was over the top.
