I am just wondering if anyone has some good tips for achieving an ultra-realistic effect when rendering a person's head ? An example of truly realistic renders (in my opinion) would be some of Syyd Raven's promotional images at the RuntimeDNA store. Some of things that detract from realism in the images that I create are : * Glassy eyes; * Glow emanating from mouth and nostrils; * Stiff, plastic-looking smiles (as opposed to, say, DAZ's freebie smile pose, which looks truly natural in the promo); * Teeth that are too perfect (even dentures don't look that fake); * Unable to get right combination of lights; * Camera positioning. Any feedback would be appreciated. thanks, Andrew
