Ragazzi neanche un off topic sull' arte ? Ci penso io a metterne uno....
Sapreste dirmi se la tecnica usata per dare risalto ad un solo particolare tramite l'uso del colore ha un nome ?

Un pò come gli effetti di "Sin City" per intenderci.

How do you create a black and white image with spot color as seen in films like Pleasantville and Sin City?

The image opposite was done in Photoshop, for my business card. However, it is intended to replicate a common technique used in motion picture and television grading. Usually I would be using Digital Vision Film Master software color correction, or da Vinci 2k Plus hardware .

The technique itself is pretty straight forward. In photoshop it is ok to just draw around the color area, because we are only ever going to process a single frame. For moving images this would be slow and expensive, and possibly noisy around the edges. So in a real project we isolate the color using an HSL key and then removing color from the outside (black) part of the key. The actual operation changes from system to system. On da Vinci I would first remove all the color (sat=0) then isolate the required color with an HSL keyer and add back the original color. In Film Master it is basically the same, except the system has a layer router that allows the natural color to be selected as a source, rather than a saturation control that puts back the color.

Spot Color
Early film uses (Pleasantville for example) did this the hard way by painting frames. I suspect that much of Sin Citywas also done as VFX. But if well planned it can be done quickly and effectively in color correction and I have done several jobs that would otherwise have been fx intensive.

Grazie mille, stasera provero la sperimentazione.
