Recent developments on physically accurate, unbiased raytracers --- and more to the point, GPU powered raytracers that provide near real-time, interactive manipulation of fully textured and shaded models and environment --- promise an unmatched workflow that makes the creation of super-realistic images and animations very easy. I won't write much about the technologies behind them, but I think the video below is a great example of some of the things that become possible for a single person using commodity technology and hardware --- in this case Blender and Octane Render (one such raytracer), especially given how much of the lighting setup and performance trickery, that would otherwise be absolutely necessary, are 'handled for free' by the renderer.
