![]() ![]() Rather than simply use Gaussian noise characteristics for the profile, DxO derive complex grain matrices directly from the real crystals of silver halide in the calibrated test images. This is where DxO FilmPack sets itself apart from the competition. Once the films have been returned, a similarly rigorous controlled digitization process is begun with the object of defining calibrated colormetric and grain profiles for each film. ![]() Using two labs enables a consistent spectrum of variation to be compiled. Why two labs? Because there will be slight variations between the labs. The retrieved film is then exposed under carefully calibrated lighting in lab conditions with the resulting rolls sent to labs in New York and Paris to be developed. It takes a special kind of dedication to track down the last rolls of obsolete unexposed film stock, but that is an integral part of DxO’s process. ![]()
