21st century work mostly uses digital cinematography and has no film stocks but the cameras themselves can be adjusted in ways that go far beyond the abilities of one particular film stock. They can provide varying degrees of color sensitivity, image contrast, light sensitivity and so on. One camera can achieve all the various looks of different emulsions, although it is heavily argued as to which method ofcapturing an image is the "best" method. Digital image adjustments (ISO, contrast etc.) are executed by estimating the same adjustments that would take place if actual film were in use, and are thus vulnerable to the cameras sensor designers perceptions of various film stocks and image adjustment parameters
