Hello all!
I have a particular problem with a film shoot I am in R&D on at the moment. I need a few of my characters' skin tones to have an infrared quality to it, but want the rest of the scene to be in normal visible light. So it's literally only the skin that is infrared.
See image for reference:
Infrared images of skin have a certain waxy, white, smooth (removal of blemishes because of the lack of colour in the red channel), almost translucent, and have a glow to them. If this was just a still image I was trying to create, it would be simple I would just isolate and mask out the skin area and composite it on an image shot with visible light...but alas it is moving image so everything becomes a hundred times harder.
i am looking for thoughts on filters and colour correction combinations that might successfully create this look in Photoshop, then I can either use the theory in another application like Nuke or Fusion...or even attempt it in Photoshop. A simple fake Infrared channel swapping is not good enough, I need that waxy look. It's not simply a case of colour correction I think.
Any thoughts would be most welcome.
many thanks
Tim
I have listed below how I planned to do it in-camera if snyone is interested.
I have a Methodology to do it in-camera but it's very problematic, and involves using a 3D stereo rig with two cameras, one infrared converted, the other a standard camera. There are many problems to this method, like the difference in focus distance between visible and infrared, the exposure compensation that would be necessary, the issue of getting the right amount of infrared light needed to create a clean image. Monitoring restrictions, weight, logistic and cost of using a 3D rig. Managing to convert a camera to infrared that is 10/12-bit with a wide enough dynamic range necessary. I am looking into converting one of my Blackmagic Cinema Cameras but there is no genlock for shutter sync (but not majorly worried about that as for this purpose I could probably get away with it.
i am also considering VFX workflows Like 3d scanning the talents head and texture mapping a series of infrared image maps onto the 3D model then tracking that onto them over the live action footage. One idea I toyed with was to turn an image into B&W then uses that as a grayscale map to use as a luminance value mask to map an infrared image map over the footage but I doubt it would work Very well if at all, and as soon as you start getting motion blur and or even noise it would throw it out.
Thanks
