Filtered

This is the filtered picture:

The saturation of blue areas is enhanced, while that of the yellow-red is exponentiated:
 
  1. ExpSat(hlow=190,hhi=220,exp_s=.5)
  2. ExpSat(hlow=220,hhi=60,exp_s=2)

Test

Selection of the blue -> yellow portion
for testing purpose:
 
  1. ExpSat(hlow=220,hhi=60,exp_s=2,
    test=true)
