Figured out a better way to create a reference template to feed into G’MIC’s Packed Ellipse preset to create these type renders. Inching closer the the Ben Heine result I’m going for, but still it eludes me. Yes; lost my marbles many years (well to be honest, decades) ago, but continue to fine them while as I search. lol
Part of the process of creating the marbles is using the original image and converting it into a convolution layer to set to grain merge (part of the secret sauce). lol
Yes; it does add noise, but in this case, the noise is intentional. lol
The trick is I use a rendered target layer to create the circles with and then turn that result into a b/w mask by extracting the alpha channel. I use that mask along with the original image and apply Blend (Shape Average) (G’MIC; David was kind to preserve this preset for me when he went another director for colorization; I like this method better for what I use it for) to color the white dots with the average colors that’s within the mask’s whites. I then use Bevel Reflect Logo (a cool plugin with cooresponding Script-fu that Gnutux (creator of the GIMPChat forum but haven’t heard much if any from him when he sold his site since he couldn’t maintain any longer). Can find that cool plugin on GIMPChat; not sure if anyone’s ported it to GIMP 3.0x, but I still use 2.10x. BRL creates the marbles. I then do some convolution tricks to give the result a more ccontrast/sharper look.
