Top of the morning to you, Sir, from Australia.
I'm not an enthusiast of the B&W genre, but this doesn't mean I pass up opportunities to look and your references are very satisfying. I very much appreciate considered technical work, and your representative image is very appealing indeed: the smooth, symmetrical almost Taoist-like contortions of the rock strata are very eyecatching. The thread caught my attention because I have friends touring the USA and have just reported their walking journeys around the Colorado River at Page and Slot Canyon. There were others they reported on: Antelope Canyon (Utah). This has been well visited by LF photographers from Australia shooting in B&W and colour.
