I was experimenting with Hugin panorama software lately. I was able to produce nice panorama views in flat horizontal plane. Very intuitive software. I just also tried spherical panorama and it's having a bit of troubles aligning pictures. I believe this is due wrong settings I have (default settings) for focal length and focal multiplier They're set to 4.105 mm length and 5.54x for multiplier. I was searching on the net for those specs for Phantom 3 Standard. Cannot find anything. Could anyone advise on those two values ? Thanks. Tom.
