Filmed with 12 gopro black edition. This kind of bullet time is possible cause we have published a software home made. Normally bullet time is created with a lot of cams. We found a solution to use only 12 cams. It's possible with any cam or synchronized DSLR. We chose gopro cause we wanted to make bullet time in aqua shooting.
