after...

Revision Two.  Here is the same photo, completely revised in Photoshop Elements with the color cast removed.  Whereas Gaussian Blur was applied in the previous revision in GIMP, only Lens Blur was applied in Revision Two.  Yes, layers and multiply were again used.  I think I prefer this version of the photo... or, at least, I prefer Lens Blur to Gaussian Blur.  My opinion has nothing to do with the programs themselves.  Only technique.

After...

Revision One.  I employed layers and "multiply" in GIMP to bring out the details.  Then, just because I could, I opened the image in Adobe Photoshop Elements and applied yet another layer of sharpening under the enhance menu with remove lens blur selected because I was not satisfied with the print quality.  I created three different sizes of this photo - 4X6, 5X7, and 8X10 - in Adobe Photoshop Elements and selected resample option bicubic smoothing because I was enlarging a nearly thumbprint sized photo.  Print quality was much improved.  Wish I had Genuine Fractals 6!
