The Titan 2 Rig holds two small cameras pointed in the same direction. Intended uses for this rig include:
- Synchronized photos from normal and infrared cameras for vegetation analysis
- Synchronized photos from normal and Infragram cameras for vegetation analysis
- Synchronized photos from two normal cameras with different exposure settings
- One camera recording photos, one recording video
- One camera capturing wide angle stills, one capturing zoomed in stills.
- Your idea here!
The raised lips at the back of the camera trays allow both cameras to be easily attached and immediately aligned to capture the same scene. The tilting tray allows oblique photography as well as vertical mapping photos. The shoulders of the upper frame can hold electronics for synchronizing camera shutters or other tasks. All camera controls and the LCD are always accessible. Twelve brackets allow attachment of legs and bumpers in many configurations for camera protection. Legs and bumpers are easily removed or reconfigured for changing conditions (wind) or requirements (kite vs. balloon). In effect the tray has three camera platforms and is therefore reversible; this can make it easier to drill tripod screw holes for multiple camera models. Also included is a single-camera tray which can replace the dual-camera tray. This converts the Titan 2 Rig into a Redstone Rig for single-camera photography. The Titan 2 Rig is easily attached to either a Picavet or pendulum suspension.
Yvain,
I have not done anything like that, and I don’t know what is needed to scale up the system of connecting a single switch to all the cameras with USB cables. If you can get a 5.5 V pulse to each camera at the same time, then CHDK will do the synchronization for you. Another approach is to use cameras with infrared remote ability. Then you can just produce the proper IR signal and all the cameras get it at the same time. But without CHDK’s synchronization trick, the cameras will not fire at exactly the same, and I don’t think many PowerShots have IR remotes. If you Google things like “bullet time camera setup” you will find many examples of multi camera setups.

Dear Chris Fastie,
I saw your great work on camera synchronisation.
I am student at the University Of Geneva, Switzerland, for one of my project, I would like to synchronize 80 cameras and take synchronized pictures, do you know if it feasible using CHDK?
The best for me would be to have a remote control which allow to make focus and then a picture with all cameras simultaneously, do you know if I can do this?
I was thinking to connect all this cameras to an alimented USB HUB and finally plug a button on it but I don’t know if the signal will be send to all cameras or not, and how can I handle this…
Thank you for your help,
Yvain
