Frage von aight8:
I understand that right? With Black Stretch is one dark area reserved in the Picture a better contrast and Knee is the same area reserved for light?
Your use this feature (if you have it;)), one can not simply strechen Kneen for the Postprod or;)?
Antwort von Axel:
One can only in the postproduction process the what "is there" (drink, what is clear, eat, what to do, say what is true, take what's there). In the case of over-or underexposure occurs in electronic signal processing to the so-called "clipping": An overexposed area is suddenly (and often with ugly border) WEISS, without drawing (camera synonymous people say "eat up"), a dark one is black hole, which swallowed up all the details (synonymous as "drown" means). With Knee and Black Stretch tries above all to force a transition to the small clipping. The real salvation lies in an exposure, through both in the dark as synonymous in the light parts drawing. You can reach the * n * u * r * by a scaling of the brightness values on the of the Camera detectable aperture size
in front of the camera, either lightening to dark parts (lamps, reflectors) or dim to bright parts (shading, ND spot filter). The next stumbling block is that one away with a "safe", without any slack Picture contrasts Dynamics. It may almost entirely black and white, almost giving in the Picture. You see, it is more complex than a simple preset.
