Here is a close-in animation.
It's just 120 frames, 4 seconds.
It demonstrates realism in close
with strand hair.

Hair model: Kate Hair
Render settings:
Raytrace on, 2 bounces
Min Shading Rate 0.00
Pixel samples: 5
Bucket: 32
3 spotlights on face, two casting Depth Map shadows
Map: 256, bias .01, blur 6
Hardware: AMD 3500+; 4GIG RAM; Dual Raptors; XPPro; NVIDIA GeForce5600 256MB
Average rendertime per frame: 525 seconds = 8 min 45 seconds

Quicktime, 1.5 MB

Known problems:

1. flicker in the fine shadows cast by whispy hair.
2. inadvertent animation of items reflected in eyes.
3. head transit slightly too fast, and ease out not deep enough, more overshoot needed

Other than that......
Shheeesh, a lot can go wrong in animation.
But I am not upset, this was just a practice animation.

I was so happy to get the render time down to 525
seconds, on average, by zooming in on
the shadowcams, that I probably re-entered the
flicker zone. The maps were only 256, although
bias was very low (.01).
