Possibly The Cheapest Way To Film In Bullet Time

When The Matrix hit the cinemas back in 1999 it started a minor revolution with its use of so-called “Bullet time” — a freeze-frame technique in which the action could move round a momentarily frozen subject. It’s filmed using an array of cameras in an arc, something which was pretty expensive back then but is now within the reach of almost anyone. Just how cheaply bullet time can be filmed is shown by [3DSage], who turned nine toy cameras into a budget bullet time rig.

The cameras themselves are what you might expect for the princely sum of nine dollars, but as he points out, their low-resolution video has a certain charm. Some iteration was required to produce the rig without fouling their flip-out screens, and he found that the video quality was far better than their still image quality. But eventually he was able to extract the required array of frames and stitch them together with a video interpolator for the required effect. His cat is a handsome creature from any angle, we can now reveal.

The video below the break has all the details, and while we couldn’t spot quite the same camera he used on our local version of the online shop he used, there seem to be plenty of similar cheap devices should you wish to try it for yourself. Either way, this cost much less than the previous budget bullet time contender.

Digital “Toy” Camera, Made For Tilt-Shift And Other Analog-Like Experimenting

Like many others, [volzo] loves playing with photography in a playful and experimental way. Oddball lenses, vintage elements, and building from kits is what that world looks like. But that kind of stuff is really the domain of film cameras, or at least it was until [volzo] created his Digital Toy Camera design. The result? A self-built, lomography-friendly digital camera that allows for all kinds of weird and wonderful attachments and photo shenanigans.

3D-printed mounts and magnetic attachment makes swapping parts a breeze.

To make a DIY digital camera that allowed that kind of play, the first problem [volzo] had to solve was deciding on an image sensor. It turns out that sourcing image sensors as an individual is a pretty cumbersome process, and even if successful, one still needs to write a driver and create things from the ground up. So, the guts of [volzo]’s creations use the Raspberry Pi and camera sensor ecosystem and M12 lenses, a decision that allows him to focus on the rest of the camera.

3D printing, a bit of CNC machining, and some clever design yields a “toy” camera: simple, inexpensive, and enabling one to take a playful and experimental approach to photography. The design files are available on GitHub, and there are some neat elements to the design. Magnetic mounts allow for easy swapping of lens assemblies, and a M12 x 0.75 tap cuts perfect threads into 3D-printed pieces for M12 lenses.

Heat-set inserts also provide robust fastening that can hold up to disassembly and re-assembly (and don’t miss that our own [Joshua Vasquez] has shared how best to design for and use heat-set inserts.)

[volzo] has a fantastic video to accompany his project; give it a watch (embedded below, under the page break) and see if you don’t come away with some inspiration of your own.
