Hmmm I'm not sure if that's quite correct, but I'll defer to your greater technical knowledge. However, look at how the green bushes are rendered in the various conversions. In the LAB conversion they are very, very dark to the point where shadow deatil is gone in some areas. That seems

In BW we can affect contrast and gray-level representation of color with the use of filters. Some on the camera, some on the enlarger. What I'm thinking of is really a question about the raw format. Is it truely raw, the simple captured sensor data. If it is, are there techniques in place to

I've also found that changing the temperature of the light in the RAW converter will affect the look af a subsequent BW conversion. You can also adjust individual color values, which again will afftect the way they convert given a specific channel distribution. Paul On Thu, 2 Dec 2004
