The original idea came from, with thanks, Itai Nadav in his post. I just copy cat with fisheyes JPG and English display.
[This method has drawback, see bottom remarks]
Please prepare 2 photos mount taken with photogtapher stands at different position.
We will use Snapseed's Double Exposure, follow by the latter's Undo with Brush.
Then Snapseed's HDR is applied to the fisheyes.
Finally, stitched with Misphere Converter. By this process, the stitch line usually after HDR (differece in exposure, etc, across the border of a stitched flat pano after drastic editing) will be damped down.
However, the process does not remove/ mask the base image completely and leaves a ghostly shadow if it is too contrasting. Use with care.
