My father-in-law was telling me during our trip that black and white is unforgiving, and although I am not entirely sure what he means by that, I am sure he is right. I think it might be even worse with a digital camera, but I am not sure. It just seems to be hard to maintain much detail in the highlights (I had to use some PS brushes to bring back detail on the bare branches at the top), though in this case I think the polarizer helped by really darkening the blue sky and creating more contrast.
