nice! how did you manage to get the pentagram-shaped bokeh on the
defocus? (i.e. the apeture shape?)
(been out of the loop a little, but last time i used some dof, the bokeh
came out perfectly square-shaped)

Nice of you to notice! The dof and bokeh effects were done as a bit of
post-processing in photoshop using dofpro
(http://www.richardrosenman.com/index.htm) - it gives much nicer results
than the blur_samples function in povray. I used the megapov post
processing function to produce a depth map and then used this in the
plugin. The details are on my web site:

excellent!
so, did you render an 8bit image out of povray?
Ideally you'd render a float precision image so you can get all the
out-of-focus hilight shapes just as bright as the in-focus hilights.

Sorry - I have no idea what you are talking about - sounds good though. How
would I go about doing that? I could then re-render and see the
difference.

The jaggies on the checkers kill it as far as realism go. Maybe a marble
checker board would make this less visible, or higher AA settings. The rest
is so real though. good work!

Thanks. I think it may be a problem with the image as a JPEG rather than a
bitmap. I'll check when i get home!

Nope - not a problem with the jpeg - bugger. I've tried a few render tests
with higher aa - changed the sampling method to 2 etc but I can't get rid
of the buggers...oh well ! Any ideas welcome!

It is probably the HDRI that is causing the jaggies. The white squares are
just too bright.
To get rid of the jaggies, you can render at a higher resolution and then
downsample the image.
