Yes, you read this title correctly. And yes, this post is about what you think this title means: using two Lomokinos to produce 3D analogue movies. Or at least I tried.
WARNING: you will find this post rather boring if you don’t have red/cyan anaglyph glasses.
Building a StereoKino
Most of the steps and material used are identical to those involved in the construction of a Power-Winder, except that you’ll obviously need twice more of them. If you intend to experiment with stereoscopy, here’s a useful read. I won’t bother you all the steps and I think the following gallery is explicit enough. If you have any question, I’ll be happy to answer.
Before shooting, mark your left and right camera and film to avoid any confusion.
Once finished, the StereoKino looks and sounds like this (you might want to turn off the volume):
First, scan and crop your frames as usual. The left camera being upside-down, you’ll have to rotate those frames. Import your frames in a video editing software, placing the left on top of the right ones. Change the RGB settings of your frames (Left: R100 ; G0 ; B0 – Right: R0 ; G100 ; B100), and change the ‘layer mode’ of the left frames (now red) to ‘difference’. This is very simple, and clearly explained here.
It would be wonderful if it was that simple, but it isn’t. First the cameras were not synchronized, second each camera was shacking because of the motors and third the automated crop caused small movements and shifts in the resulting frames. It was therefore necessary to realign each frame, and in some cases repeat some frames when one camera was going too fast. Out of all Left/right pairs, a few were lucky matches:
The majority was quite messy, didn’t really produce the desired stereoscopic effect but rather a headache… I still had some fun building it, and it can be used ‘normally’ by unplugging one of the motors.
