Q. I am thinking of making my own 3D camera, and will use red/blue glasses. I am going to buy two Muvi Micro Clone type camera, and want to know what distance apart the two lenses should be for the best quality video?

My plan is to use the camera as an action camera, to record 3D cycling videos mounted on a bicycle helmet.


Anyone got any advice :) Thanks!!


Answer
I have to respectfully disagree with lare on that one - you can do 3D without synchronised shutters. Have a look at Suzi Perry's 3D video, recorded for The Gadget Show. This was shot with a pair of Canon 550Ds. I seem to remember the program mentioned all sorts of potential problems, but the results were much better than expected. From what I remember, the distance between the lenses wasn't critical, but they had to be aligned so that the images seemed to converge at the right distance. I don't remember what the right distance was though - sorry!

A good camera for my commute to work?

My budget is up to £150, ideally under £100 though. I want a camera that will fit either on my bicycle somewhere, or on my helmet. The quality needs to be good enough to read plates and get detail of peoples faces. I also want the battery life to be around an hour. And the camera cant be too big either. Anyone know of any?


Answer
The GoPro is a very popular brand that does what you want, but you'll have to up your budget.

To stay in budget you might have to build your own bracket for the bike or a strap for your helmet.
