no, I'm not trying to see it in 3D, what I need is to see both pictures to make better adjustment between the 2 cams.DavidGhast wrote:what exactly is the point of this device, to see a 3d image on a 2d screen? thats not going to help you see the disparity of your scene.
that would be nice but it's not what I need, I have to see clearly both images to adjust their onscreen position, also it doesn't look much easyer to build as you need to find a way to connect both cams on the screen and make that flipping effect between the 2 of them would be verry complicatedcybereality wrote:Ok, what about a pass-through type device that could quickly flip between two source signals. So you would only need one portable LCD screen and the device would sort of multiplex the signals into one constant stream that alternated between each view. Seems a lot easier to build then the double-screen device you are talking about. So it would look something like this:
I'm sorry, I don't understand what "IO" isDavidGhast wrote:why are you worrying about IO on your setup when you dont have a slide plate to adjust it?
that's what I was trying to do untill now but it's not working for me, it's too hard to align the cams with the fixation I made and without seeing both screens properlly, I hope it will work better after a few changes.Tril wrote:For a specific zoom and a specific distance between the cameras, there is a distance at which what you film will be at screen depth. Closer to the camera will popout and farther will be in the screen. You could experiment with different zoom and distance between the cameras and note the screen depth distance and make yourself some table with the data. Then you just have to use your data afterwards. It should work as long as your cameras are always well aligned the same way.
I'm not sure about the necessity to adjust that, I still hesitate between fixing it at 6.4cm (about 2 or 2.5 inches) and an adjustable rig, I think it's better to have adjustable convergence but I'll see, if it's not too complicated then I will another way that I was thinking about to adjust separation but I'm afraid that to many moving parts could become a problem for such a rig that I want to be able to transport and manipulate a lot wich can be tricky if too many parts.DavidGhast wrote:IO as in interocular, the distance between the foci of the cameras. If your cameras arent on a slideplate, then how do you intended to adjust them?
If your hoping for a consumer level stereo preview solution, then you're going to have to wait a decade or two. The cheapest way to go is to do alot of testing and get a feel for what you will need in a given shot without actually seeing it.
