I am finding the current B&W challenge interesting but difficult (to make something new look old by using b&w). I have made a few unsuccessful attempts where b&w conversion makes things look older but where the colour version still remains more appealling, and also some examples where b&w makes actually the subject look more modern than it is.
This shot is my best result so far : thanks to the use of b&w and to the scarcity of modern objects in it, this landscape picture amost looks like if it had been made one century ago.
