He encontrado esto, pero no me queda claro
The Nikon D70 profile above, for example, seems to requires Gamma 0.45 and Linearity 0.00. It seems that the Phase One curves also require Gamma 0.45 but with Linearity 0.05. Also enabling the use of color matrix with these profiles gives interesting results.
For each profile you can choose if you want to use the Color Matrix. The color matrix is used to make a linear transformation from the sensor's color filters to standard RGB. UFRaw gets these matrices from DCRaw, which in turn got most of them from Adobe. Usually you will want to use the Color Matrix with RGB profiles and not use it with camera profiles.
Notice that the Color Matrix and the gamma curve are applied before the ICC profile transformation. The reason that they appear after the Input Profile is to emphasize that these settings are defined per profile.
¿Alguna aclaración?
