Welcome to Fractal Forums

Hi, I'd like to Paypal $15 USD to someone who can re-create for me the fractal image seen here:
http://commons.wikimedia.org/wiki/File:Time_escape_Julia_set_from_coordinate_%280.285,_0%29.jpg

I've been seeking to get in touch with Solkoll, the original author, however it seems that they've been inactive in the scene for a few years now, and have left no working contact.
Thankfully, as is said on that page:


So, I'm looking for a very large version of the image, on transparent background, that also replicates the colours. So, exactly what is shown there, in high resolution, and on transparent background. The file format should be tiff, or some other lossless form. Resolution size ought to be 6000 pixels in height.

If someone is able to do this, I may be interested in multiple colour schemes, for which I'd pay an extra $5 each - to be decided after seeing other colour schemes. Replies can be posted here, though for more immediate attention, email me at delicieuxz*at*hotmail-dot-com, just remove asterisks of course, and adjust the rest. Cheers!

the 8000*6000 tif image is 36Mb big.

I dont understand. I did not receive the $15 on my bank account :D :D

Lol! I only just checked for replies. If you'll pm or email your paypal account, I'll send you the $15 for the tiff, even though you posted the details, you still did the service  :dink:

Please send the money to Trifox for the forum.

the paypal account is my email adress, thx bib

Sent, cheers.

Could some tweaks be done on the fractal image before sending? I made a pic to show what the adjustments are, with the target on the right.

(http://i42.tinypic.com/jj2tkn.jpg)

you are maniac !!

Those sorts of tweaks could be done much faster and with far more control in an image editor.  While adjusting the color gradient is tricky - it can likely be done in a fractal generator.  But changing the orbits (those curved lines) will have cascading effects on the rest of the image.

Take the picture into an editor and play!  The Gimp  ( http://www.gimp.org/ ) is a powerful and free one if you need one...

I'm intrigued, why do you need such perfection?

OK,

What about this one ?

Impressive! That one appears to be spot on apart from being a bit darker coloured. Could the high res version be uploaded to mediafire or some other download service where I could grab it? I don't have a fractal program and haven't learned how to use one either way.


I don't need a 100% replica per say, but it's the aesthetics of the original that made me interested in a high res version, and the first example is a bit less attractive when compared side-by-side, imo.

My receiving the image file was an integral element of the commission, lol. If you could email or pm me a link of a download source, that'd be great. Even if I downloaded a trial version of Ultra Fractal and looked into how to apply the settings, the UF website says that trial version images are branded. Basic accounts at Media Fire and other file hosting services are free.  ;D

Can anyone render the above UF parameters for Delicieuxz please ?
I am in holidays and did not bring my PC.
Thanks for the joint effort!

what resolution do you need it ?!

I believe it was requested at 6,000 x 6,000.

Like this:

 Hope that's it! O0

That is unquestionably a thing of beauty! Thanks for the upload, I just need it on transparent background rather than white. Other than that, c'est magnifique! And bib, thanks for the work, man.

Not an easy task, given the way the white fades slowly to blue in many places - determining the cut off point and edge quality is going to be up to each artist and will look subtly different depending upon who does it.

There is no way to get a sharp edge, so I gave it a soft edge and if it's not what you envisioned - you may need to cut it out yourself with any image editor at all  (they all should have tools to select by color!)

Here's my best effort:

I used a value of 20 for tolerance in rgb variations and a 1 pixel feathered edge.

Hope it works for you  :yes:

I was thinking the fractal program would have an option to choose a transparent background, but what you've posted is quite fine enough. Thanks, everyone, it's gorgeous!

just received the 15$ :D
i will silently use it for paying the hosting bills, thank you for your generousity bib and delicieux

if this is going to be something like ebay, we have to make it other ways :D

@delicieux, i think i did not accept the transfer, if so, please submit again ...

You can also try rendering this:

A few more gradient points, with the opacity linked gives a pretty solid transparent rendering version.
