STITCHING DUAL FISHEYE IMAGE TO 360 SPHERICAL

Hi everybody,

I'm lookink desperately for a method to stitch dual fisheye 180° image (jpg) to 360° spherical image (dng).

I've made a wrong manipulation formating sd card (thinking it was just a jpg to raw format modification).

I've used stellar photo recovery but I've obtained dual fisheye 180° image jpg and I'm not able to rebuikt 360° spherical original image.

Is there any simple solution ?

Thanks everybody by advance

Best regards

Jean-Marc
