Callum, Using three lenses, my Blenders produce a collaged panorama, not a traditional panorama per say. Each lens flips and reverses its image producing a long image of a 180 degree field. The evenness of light in your finished image would depend upon the light at each lenses field of vision. Here's the tricky part. Each lens has its own view that is flipped and reversed. What is on the left for the center image is flipped and reversed so that it is now next on the negative to the area from the right side of the right lens. That is why I call it a collaged panorama. The focal length is approx. 60mm with a .3mm pinhole making the aperture f200. Exposure charts can be found at my site, http://www.pinholeblender.com Instead of the magnets I sometimes use black photo tape or electrical tape. Presently I'm working on a 6 hole camera that takes 4x5 and a 35mm version. Check out the website in the next couple of week to see these. I'm available on or off the list if you have anymore questions.
