When taking photos of cloudscapes or aerial landscapes, I almost always have to adjust the exposure - either increasing or reducing the amount of light. The light meter in the camera tries to set a grey midpoint. If you allow it to do that with clouds or light colored scenes, you end up with grey or muddy brown clouds. Even with photoshop, I've found it's impossible to correct the exposure enough to get the clouds back to white. So I check the histogram after every photo and use the exposure compensation feature to add more light or reduce it if anything is blown out. When there are clouds in the scene, I make sure the histogram is strongly skewed to the right, with a significant proportion of the distribution in the upper quadrant. That ensures that the white clouds are white.
