I posted this awhile back, but it needed better antialiasing.
This one (1280x1024) uses method 2, depth 4 with a
threshold of 0.01, took about 10 days to render, but there's
still jaggies. It's about 1Mb (change the "png" to "bmp" for
the original):

Any ideas and suggestions greatly appreciated...

I don't have an idea how you can enhance even more such a stunning quality.

I would like to see the spiral track of the record but know that for very
thin and close lines, it is lmost impossible to avoid strange interferance
artifacts.

Congratulations !!

need threshold 0.0 (be sure to specify 0.0 and not just 0) and as far as I
can tell, a depth of 2 would be sufficent (and a lot faster).

Wow.  ;-)

Nice work.
Did you use a focal blur camera
some of the writing might be cleaned up if you up the samples etc in the
camera...if you did use a blur cam.?

No focal blur was used. The original scan of the label is
pixelated (I found it online), so maybe I'll try some clean-up
some day, or try to do a better scan myself with a different
label, I have no Blind Lemon Jefferson records myself.
