Stitching photographs of a 18mm lens is complicated and takes longer to make a QTVR or with the appropriate program does not require much time.
The program recognizes once all the photos or you need to identify common points between the photos?

what is the best program that recognizes best the common points of the photos?
To make a 360 degree spherical, first I stitch the photographs in a program and then along the upper and lower picture into another program?
Can anyone help me

Thanks
