You know those videos you watch and think: “No way is this real, it must be some kind of magic?” A short movie Box by Bot & Dolly will make you feel this way. It’s an awe-inspiring video created with robot-powered projection mapping on moving objects. It transforms two moving flat panels into all kinds of optical illusions, bending, flying and teleporting across the stage. And as for the interaction of the actor and the illusions – there’s no CGI, but everything was captured in-camera.
Have you ever seen a helicopter magically rise in the air without its motor spinning? If not, you are in for a treat. OK, how can that be?
Here is a little well-known secret, the main rotor of the helicopter is actually spinning pretty fast? Fast enough that it perfectly aligns with the frame rate of the camera.
Time to dust up on your Color Balance Adjustment Layer. Here’s a quick Photoshop trick that will add some more magic (or magical fire and ice) to your composites.
This technique works wonders using dust particles shot against a back background. You can shoot this yourself or use a pre-made dust resource if you don’t have the energies to vacuum all the mess such a shoot creates.
Interesting things happen when you combine makering with photography. Take this project by science channel brusspup for example. He has a neat way of making water flow in some weird ways, with the topping on the icecream being making them flow backwards.
So, how does it work?
The first part is tone generator. Brusspup is using a homemade device for that, but you can use an online tone generator. Tones are generated at 24Hz (that is 24 peaks a second). Those tones are fed to a hose via a speaker. Now the hose is generating a waveform, but we can’t see it because it is constantly changing.
The second part is the camera, which runs at 24 frames per second. You can think of a 24 FPS camera as a stroboscopic device that takes 24 images a second and freezes them.
