The best Dehancer grades are often dialed back.
Here is a critical distinction for post-production professionals.
You might think these two processes are opposites, but in a professional workflow, they are partners. Many colorists will de-noise the image first (removing ugly digital compression artifacts or thermal noise) and then apply a quality dehancer afterward to reintroduce beautiful noise. quality dehancer
Why? Because digital noise is ugly (blocky, static, color-shifted). Film grain is beautiful (random, dynamic, warm). You cannot polish digital noise into looking like film; you have to replace it.
First, let's correct a common misconception. A quality dehancer does not simply "reduce sharpness." It is not a blur tool. The term itself is a clever counter to "enhancer." While a traditional enhancer adds edge contrast and saturation to make an image pop, a dehancer removes the clinical hallmarks of digital capture. The best Dehancer grades are often dialed back
A sophisticated dehancer simulates the photochemical process of analog film. This includes:
A cheap plugin will just slap a layer of monochrome noise on top of your video. A quality dehancer understands optics. It treats the image as if it were light hitting silver halide crystals. You might think these two processes are opposites,
Never judge grain on a scaled-down image.
