When I “developed” that picture with my favourite piece of software (Adobe Lightroom 4), I hesitated a lot as to which kind of rendition I’d choose. At first, I really liked the original picture below.
Rendition 1 (above) is therefore untouched. Except for straightening vertical lines very distorted by my wide angle lens.
(Rendition 2: above) Then I tried to work on a copy of that picture using the “colourfade” preset (download link below text). It sorts of enables you to turn your picture into a black & white still + 1 (or 2) tones. Here I tweaked the preset in order to add the blue sky. I thought looked great because it then highlighted black figures against a blue sky and at the same time, there was these special grey tones in the corners.
Rendition 3 (above) was even more radical, and I assumed that what mattered was the Chinese shadow-type characters in the picture and the blue sky was only there to distract the eye of the reader.
Now is a good time to decide which picture you prefer and vote:
