I installed the trial version of Imerge Pro. As there is no real tutorial, I had no idea of the workflow. The user manual seems to be a joke.
I have 2 images, a girl on a blue screen and a forest background. I apply a chromakey effect on the image with the girl, but there are 2 problems. First, a part of her head is transparent, I see a tree behind. Second, I have artifacts on the girl image, and I do not know how to delete them. Very easy in Photoshop, no idea how to that with Imerge.
I am happy that this is a trial version.
