The best definition of the mastering this art has been described, analyzed and practiced by Ansel Adams as he have extendedly explain in his book trilogy: the Camera, the Film and the Print.
I will not pretend approaching Ansel Adams artistic ability but I think that if you are doing good black and white pictures it can improve deeply your entire photographic skill even in color.
Here are some recent works with the Olympus OM-D E-M5. All pictures files are originally done in black and white.
|Snowfall over the bridge|
|Minette face in B&W|
|Cross lightning over the balcony|
|Black and white photo painting of the river in winter|
