For the normal person, blue skies make for a lovely day, but for the landscape photographer, they can be pretty drab and boring. That does not mean you can't take great shots, though; it just means you need to try for different images than you would otherwise. This great video discusses how you can turn monotonous blue skies into fantastic images.
Coming to you from Chris Sale, this excellent video discusses how to handle blue skies as a landscape photographer. No doubt, blue skies can be very peaceful and pleasing in person, but on the other hand, that does not always translate into a good image. One great trick Sale employs is switching to black and white in these situations. With black and white, you can stop worrying about dealing with the large, monotonous blue blob and instead work purely with luminosity (which often vary a bit more toward the horizon) to create compelling photos. Check out the video above for the full rundown from Sale.
