* direct : we found in this case "applyproc" modify data with low amplitude : BlurNoise, CBDL, Denoise, Sharp, TM
* with first use of "buflight" on which is apply "applyproc", in this case we apply realstrdE = reducdE * buflight with a function of type 328.f * realstrdE
* in this case we found "applyproc" which result in direct use on Luminance : Exposure, Color and Light, Shadows highlight, SoftLight, Localcontrast
* with second use of "buflight" on which is apply "applyproc", in this case we apply realstrdE = reducdE * buflight with a function of type fli = (100.f + realstrdE) / 100.f;

/* comment on processus deltaE
* the algo uses 3 different ways to manage deltaE according to the type of intervention
* if we call "applyproc" : the datas produced upstream in bfw, bfh coordinate by the function producing something curves, retinex, exposure, etc.
* direct : in this case we use directly the datas produced upstream by "applyproc", with only a regulation produce for deltaE by reducdE
* direct : we found in this case "applyproc" modify data with low amplitude : BlurNoise, CBDL, Denoise, Sharp, TM
* with first use of "buflight" on which is apply "applyproc", in this case we apply realstrdE = reducdE * buflight with a function of type 328.f * realstrdE
* in this case we found "applyproc" which result in direct use on Luminance : Exposure, Color and Light, Shadows highlight, SoftLight, Local contrast
* with second use of "buflight" on which is apply "applyproc", in this case we apply realstrdE = reducdE * buflight with a function of type fli = (100.f + realstrdE) / 100.f;
* in this case we found "applyproc" which result in large variations of L : Retinex
* if you change you must test before
