Wow.. thank you for this detailed info.

My goal is to project the images into a large screen or TV...

If I use the double lens camera, do I still need to use a special software??

If you use a 3D camera that takes two digital images like the Fuji W3 then what you get is a single digital image that contains both the left and right images. The file format is .MPO. This camera come with some software but StereoPhotoMaker is more useful.

If you take the images using the cha cha method you get two individual image files.  If you use dual lenses to put two side by side images on a single camera sensor then you need to crop the image to give you the two separate images.

You can use the free StereoPhotoMaker software to combine individual images into a single side by side JPG, either left/right or switched to right/left for cross eyed viewing. The software can also combine two images into a .MPO file format.

The best 3D TVs very rapidly show the right and left eye images. You wear glasses that synchronize with the TV so each eye only sees the appropriate image and your brain combines the images to produce a 3D image. If you have a 3D TV like this then it may be able to display .MPO files as 3D images. I don't have a 3D TV and don't know if they can display any other image format in 3D.

If you have a regular TV then you can use cross eyed images, or anaglyph images if you have the red/green (actually cyan color) glasses.

eBay - Anaglyph Glasses

It took practice but I can view cross eyed image on my 24" or 25" computer monitor or on my 42" TV. I do this since I don't get any color artifacts the way you do with anaglyph images.

For cross eyed viewing on my normal TV the two side by side images must be switched and saved as a single JPG image that will be displayed. Since both images are displayed from a single file each individual image will only be half the width of the TV.

There is a limit to how big an image people can view cross eyed. The relative size of the images varies with distance. If you get too close to the TV the relative size of the images gets to be too large and viewing cross eyed images in 3D becomes impossible.
