Hi, I use Huawei P30 pro to make HDR picture and there is the result :
I use the following script :
Mat fusion = new Mat();
MergeMertens mergeMertens = Photo.createMergeMertens();
mergeMertens.process(images, fusion);
Mat ldr = new Mat();
TonemapReinhard tonemapReinhard = Photo.createTonemapReinhard(0.4f, 0.7f, 0.0f, 0.5f);
tonemapReinhard.process(fusion, ldr);
Core.multiply(ldr, new Scalar(255,255,255), response);
In other phone like Samsung S8 and Huawei P20 Lite I don't have the same issue.
Thanks in advance.
