To answer the other question, no, I don't call Moray or any other modeler a
cheat when POV-Ray is ultimately the ray tracer. I do call it a skill I lack
a lot of, me being primarily and almost exclusively a pov file script writer
:-)

| What are good settings to use for Focal Blur?
|
| Right now, i am using:
|
| camera
| location < 44.300, 93.000, 5.000>
| sky < 0.00000, 0.00000, 1.00000>
| up < 0.0, 0.0, 1.0>
| right < 1.81060, 0.0, 0.0>
| angle 43.61300 // Vertical 24.922
| look_at < -10.900, 5.100, 8.400>
| focal_point <-10.900, 5.100, 8.400>
| aperture 1.0
| blur_samples 100
| confidence 0.999
| variance 0.0001
| }
|
Those are high quality settings there, I often use much less than the best in
order to reduce render times. I'm talking about the variance most because the
aperture is the amount of blurring which is scene dependant. I'd say aperture
0.5 goes well for most typical scenes 1.0 and above become more like
telescope/binocular/microscope focuses. But it's subjective to the artist.
You might see others here have differing opinions/advice.
The samples is 2nd most important I'd say, next to aperture. And since all
this is so CPU clock-speed dependant as well then I'd suggest using a number
half your CPU MHz and go from there (likewise in variance as in 1/250 for a
500MHz). Btw, confidence doesn't appear to be as notable of change in quality
and speed I think. A value of 1.0 would do fine for the most part since the
default of 0.9 makes little difference.
Again, I think others might have other observations.
