Description

The original image is just the typical SHO mapping but I did try to enhance the color of green with curves.

The new tone-mapping was inspired by William Lequin in his IC1848. I really loved the cold feeling in grey and white and hot in red.

The mapping I used may not 100% the same as William did, so the overall outcome is also different from his. I used PixelMath to blend the H and O channels (either max or mean function was used, but I selected the result with mean), and mapped it into Red; S was directly used as both Green and Blue. With intense processing of curved, the final result looks good to me.
