So at this time of year in Southeast Qld the Poincianas are at their best. Most that I have found have power-lines or other things obscuring them. This one - on a golf course - was the best capture i found. Yet even getting down to ground level I could not grab a capture that gave me only sky behind the foliage.

My wish is to isolate the Poinciana as much as possible from the other trees. I have gone almost spinal tap on local contrast. What other approaches might be possible?

Tricky!
What I have managed to achieve in GIMP. I used the Channel Mixer to increase red and reduce green. This left the flowers lacking in saturation, so I created a mask from the red channel and used it to increase the saturation of the flowers.

Edited with Krita 5:

Used many cross-channel adjustment filter masks to separate the sky from the ground.

Dehazed (G’MIC) and Lumna Invert overay to uber saturate (yes; went overboard as I always do). lol

Second attempt. Now with oversaturating. Thanks to @lylejk idea. However, I did LAB color adjustment for this one and went with boosting the green part of A. I did more than just that. I applied levels luminosity to the ground, sharpened image a bit. Still with Krita 5.

It is a really strange and tricky picture. I can’t reach a point, where I’m really satisfied. Anyway another try:

Thank you for the play. I didn’t isolate, I just had fun.

What a wonderful tree!!

This one done in ART with, among others, the new Tetrahedral Color Warping (HSL) module.

PS. No masking used.

Hey everybody, I am blown away by the inventiveness and the variety of renditions. It is inevitable that something must be compromised. My personal pick is the second post by @Popanz because it really achieves the separation between the foliage of the Poinciana and the tree behind on the left.
@Jean-Marc_Digne, this particular Poinciana specimen has already lost a lot of its colourful blooms, however some others nearby are just coming into their best. There are some truly grand specimens over 100 years old in the vicinity of Wellington Point :

but these are almost always impossible to capture without powerlines or other infrastructure. Sadly, many have the top of the crown hacked away for powerlines to pass through!
