Black and white is good for pics with a lot of shapes and forms IMO.Certainly accentuates the feeling of desolation doesn't it! I really need to learn a lot more about post-processing I think.
It lets you just look at the shapes - simplifies the picture in other words.
I watched a proramme on photography that said it was till the 60s that colour became acceptable for 'art' pics - before that anything 'arty' was b&w, even though they had colour for nearly 30 years.
