"High quality high res photos." Just a quick "word of warning" for people who might consider using their own photographic textures in 3D... The problem with simply using photos for textures, instead of hand-painting you own, is that photographs of skin have most of the elements we're trying to achieve in 3D captured in the image. A photo of a face, for instance, already has the skin's SSS and specular properties captured in that image. So using it as a texture, you would think, is going to give you more realism with less effort? It definitely can, in certain simple lighting situations, look very real. However, it will start to fail miserably when you get into more advanced lighting or animation situations, because the specularity of your materials and scene lighting won't match up correctly with the specularity that was already "baked" in the photograph that you're now using as a texture for your character. The same with darkened areas that may have been present in a photograph of someone's face, for instance... it may not correspond with the shadows in all your scenes, and believability will totally fail. Most of the top texture creators for Poser are starting to realize this, thankfully, and are now preparing their textures more carefully by removing as many of these troublesome elements from their textures as possible. Still, some others continue to cater to the Poser 4 (and earlier) mentality of texture creation, and make textures with highlilghts on them, which then become totally useless if you're scene lighting changes in a way that no longer matches up. You can see it in the galleries, most often in the form of skin that looks "lighter" in areas that clearly aren't lit by the scene lighting. It can sometimes make the character look as if they are suffering from some rare form of skin disease. ;-) So be careful of this when you're creating your own textures, some of the "older" texturing tutorials out there do not account for it in their process. Using the airbrush and/or clone tool in Photoshop (or some similar program) could help you greatly in reducing unwanted FX from your photo textures.
