Remember that picture of the concrete mixer behind our house which I posted yesterday? Well, I felt it had to be processed a bit more, so I applied my color/b&w merging process to it – this is the result.

"The concrete mixer revisited" | Olympus E-P1 + Lumix 20/1.7 @ f/1.7, 1/80 sec, ISO 250

To see how images are affected by this process, you can compare this one to the one I posted yesterday. In essence, by merging a color and a b&w version, the luminance info from the b&w version is applied to the color luminance in the color version, while by choosing a specific merging mode, the microcontrasts are heavily enhanced, giving the image a much more dramatic look.
