The first full novel I read when I was kid was H.G. Wells' the time machine. Aside from figures of the Eloi and Morlocks, what stuck with me was the idea of the fourth dimension: time.
In photography, one can capture the first three dimensions: length, height, depth. These three are sufficient to present a simple story, painted in a thousand words as they say. But if one adds a fourth element the result can be a more complex story that can depict change in a plot or a character.
Taking a video with our camera phones, GoPros and even DSLRs is easy, but taking one that captures a change in a scene in less amount of time has more challenges. First, while the first three gadgets can make good quality photos, the video output won't be that good. Second, doing a fast forward feature on post processing results in even poorer quality videos. The timelapse machine will try to solve these challenges.
The goal of this project is to configure the Canon 70D to shoot a timelapse, a setting that is currently not available with the camera. The timelapse setting is available with other Canon models through Magic Latern and with an external intervalometer attachment. To fully control the timelapse settings, we decided to use a Raspberry Pi with Python programming. A horizontal rail will also be built to ensure that the primary subject in the photo remains in the center of the frame and to create a more dramatic effect on movement.
Here are the materials:
Canon 70D
Raspberry Pi 3 Model B
Bipolar Stepper Motor (EM 295)
L293D Driver
Breadboard, batteries, jumper wires
I'll post a sample video once available. The complete how-to will be in another post.
