Re: [Fractint] New Image

23 Apr 2017

      I've done some investigations of Albrecht's:
...
...new interesting image today [2017/4/22], created with the Oracle
VirtualXP under Win10.
The color specification of Albrecht's included parm file somehow picked up
an extra character and could not be read by Fractint, since it had become
malformed.  I downloaded his image and wrote out its parameter file with
Fractint's <b> command to get the correct color info. 

Albrecht's parms and formula, along with the parms of my variations are
below my signature.

Please view images full size.

Albrecht's image:
http://www.emarketingiseasy.com/Albrecht/2017/ML219-X3.GIF 

and my version of it (ML219-x3_FixColors), match -- except for slightly
different choices of our images' sizes in pixels.

He also recommends:
...
...check image ML219-x7, an additional entry (zoom) There are some
discoveries waiting!
My rendering of ML219-x7 matches his version:
http://www.emarketingiseasy.com/Albrecht/2017/A1704227.gif 

I was immediately drawn to the center of the above image.  What's there?
This is:
http://www.emarketingiseasy.com/Albrecht/2017/A1704228.gif 

But the empty core of the above image was a bit unsatisfying, so I tried
rotating the color map to see if anything would show up.  Indeed, something
does!  And Albrecht's nice greens that seem to go well with the purples both
reappear -- along with a slightly under-iterated minibrot:
http://www.emarketingiseasy.com/Albrecht/2017/A1704229.gif 

I liked the depth in the green "pillars" of the above image so I zoomed in
to emphasize them, and anti-aliased (X5) this image:
http://www.emarketingiseasy.com/Albrecht/2017/A170422A.jpg 
I tried increasing the maximum iteration count to further define the
minibrot, but I discovered that the color map is sensitive to the non-zero
LogMap value of this image, which changed the image radically.

Something looks amiss at " >kkammcpoe" in the last color parm line below:
