I like them especially since they are not meant to give an impression of reality. I consider black and white pictures to be a form of art. It is more the forms and shapes that make the picture. Not as much what it represents. By leaving away the colours and changing the light in the photograph the photographer has far more freedom in how to present his work. And there is a technical advantage too. When you work in low light the coloured pixels in the dark are in black and white explained as grain. :-)
In the meantime the pictures are sorted according to subject. Have fun.
