Daniel - thanks for sharing, it's not easy to put a critique of an image out for others to see - this was an excellent video with detailed explanations from Alain on what can be done to maintain the goal of dramatic B&W landscape, while also increasing it's sophistication.
While I strongly agree with the concept of having detail in the shadow, the rest was kind of silly. You don't recover shadow in digital without great penalty, as this hasty demonstration revealed.
