Interestingly enough change when using the profile created not only the colors but also the brightness / tone values. The shades are fine, many images thus appear more detailed. I'm glad to have it, although I do not always need it. Especially when incurred under difficult lighting conditions recordings it makes the post-processing easier and the results better. One does not necessarily present in every shooting create a corresponding profile, one per camera often enough, at least, if you can tolerate slight differences by the way. I think I now just, the high price is due to the complex production of color printing materialize ;-)
