achieving a overdriven almost blown out view turn into a bright yellow-white glow,
#1
good day dear friends good day dear gimply ppl. 

[first of all - i ve posted this three days ago here - and was happy to receive some nices & kind and very supportive answers - but in the mean time a serious db-crash knocked out the whole page - and  guess that 90 % of the postings of the past seven days vanished - into the dark] 

well i am currently workin on a graphic image - and i would love to get your creative suggestions! ?

after lurking here some hours - i t hought that the best would be to step up the plate and just ask: while lurking i have seen lots of great approaches to do much in GIMP: I really appreciate all the awesome threads  that i ve seen here: i think that i have to work with some kind of a layer-based approach 

see my starting point: 

I’ve experimented allready with that, and it already helped me get closer to the look I’m aiming for.

To give you a bit more context: I’m trying to reate a certain abstract network visualization style –: What I especially love is to get some behavior - at the right side  that gets some feels of - lets say “overdriven” – almost blown out into a bright yellow-white glow,   while the lines still keep a warm reddish tone. The colors are intense, but the structure stays readable.
So my question to the community: What would be your approach to achieve a kind of “overexposed” yellow-to-white transition on the right side, while keeping the lines slightly red and the overall network structure intact?


I’m open to non-destructive workflows, layer blending tricks, or even selective color grading.

love to hear from you
 
see the starting point.

Yep, used a backup and lost those posts.

I think I mentioned in a much earlier post that these small images are not the easiest to manipulate.

Keeping the linking paths is probably the hardest part. Not easy to separate the nodes / lines components. You could try something like this, but please experiment.

(1) Duplicate the layer and work on the duplicate. (2) Use the color curves RED component and pull the curve down until the lines almost disappear.
(3) Set the top layer mode to Lighten Only.  (4) Filters -> Artistic -> Softglow with maximum Brightness might just work.
(5) Colors -> Colorise the nodes.  (6) If you want to merge with the original use a layer mask (white) and draw in a black-to-white gradient.
