Here is another example showing how black and white photography is great for showcasing definition and contrast, such as in a scene like this. The storm clouds were less threatening in colour than in the black and white shown here. The reality (and intensity) of the clouds' anger was best displayed void of colour.
Bumping up the contrast a little more was all that was needed to effectively show you how the storm descended on the fields. The curtain came down and brought with it the night.
