hello CGP... i have here an image that needs a cure... my problem here is actually yung tree edges.. notice that the edges of the tree leaves are somewhat glowing due to the sun intensity.. is there a way to correct this? ignore nyo nalang yung blue background.. sinadya ko para mas makita nyo yung problem. PNG yung perspective image.. di ko tuloy malagyan ng blue sky kasi lumilitaw yung leaf edges na maputi.. sana matulungan nyo ako regarding this problem.. thanks in advance and Godbless. how to correct  tree leaf glowing edges? - Page 2 Fresse

kadalasan ito ay pag over expose ang value ng hdri or yung light cache value na nagbobounce sa object, pag white ang structure mo malakas ang na crecreate nitong bouncing light sa ibang object. since green ang trees kitang kita ito, try mo bawasan yun light cache or yung hdri intensity baka makatulong.

i suspect hindi maayos ang opacity maps ng leaves. if that's the case kailangan i-tweak ang opacity map. sharp edge ang masking (walang feathering).

my last resort to solve this is to set all to matte and -1.0 alpha except the trees para ma-isolate ang trees as a layer in photoshop. set the environment colour to a little darker than mid-gray. this color tends to blend well with any kind of background (based from experience). further tweaking the layer in ps by refining the layer mask edge (contract/expand) and feather till you get rid of unwanted fringes. you can even set the whole layer to a little less than 100 opacity (90-95) para magblend ang trees sa background ng konti.

marami pang workarounds sa issue na ito at marami na ring nai-share. hope nakatulong.
