Aww humbug. A quick investigation gave me a suspect that goes by the name of portrait background. After removing the guilty party and recalculating extends it seemed to work fine. Without your whatchamacallit I don´t know for sure. Still, no quick fix, gotta take the model back into the oven and do this real proper like. Mayhap I crank me old knuckles and make a real portrait!! Then we will see if your therapy app thar will still whine about stuff being negative!
