[Leica] Autumn Color

[philippe.orlent at pandora.be (Philippe Orlent)]

This is the first time that I read such a comprehensive description  
of why people look(ed) for a typical lens signature.
For me, this concept is hard to understand since I'm of the PS  
generation. (And I'm sure THAT is hard to understand for many of you.)
But it certainly proves that once, photographers were far more aware  
of how they had to achieve a certain result. Nowadays, it's all post  
production work.
Good for creativity, but bad for craftsmanship. As if we're starting  
with conceptual dancing without knowing the classic ballet steps. The  
running before walking thing.
Always good to be remembered of that.
So thanks for showing,
Philippe
