Great discussion. Sometimes the simplest diffusion works the best. K.I.S.S. theory applied. - Jim

I have been trying to make the perfect macro diffuser for years. I don't think it exists, keep in mind the perfect one would have to work al all magnifications and lenses. That being said I saw some that people had made that were making out of plastic document folders and attaching to the end of their lens with a rubber band and a couple of step up and step down filters. That inspired me and I made one out of a translucent document folder. Didn't work very well, but the mounting did. One I tried in the past used parchment paper as the diffusing material. For what it is worth this worked the best out of about 20 materials I tried. (I used the list from Extreme Macro) The down side is that it is too fragile to be used by itself and nothing sticks to it and I mean nothing. (that after all is the purpose of it) Well when I made this one out of a folder I had cut it. So I made another out of it folded and then I inserted a piece of parchment paper, and it worked. To make it better, I made the parchment a little smaller and then melted the two folders together. I never knew before how easy it is to cut and weld plastic with heat. (I have a heat knife coming today to make it easier) The point I am making or trying to is try sandwiching your material between two flexible pieces of plastic and melt the edges together. No glue, no sewing etc. If you want it curved like a tunnel, clamp it and then melt the edges together. Then make another bigger and attach the two with plastic strips. As for the tunnel design I did it for my table top and I used a very dense piece of plastic and wood pieces to at each end to keep its shape and it was hung from above. It worked but not as was well as I wanted. However I was using it with those worthless diffuses that attach to the flash as my first layer One you may want to try is to take a Styrofoam cup cut the bottom out and cut a cheap lens hood short and glue the cup to it. You will still need your first layer but you will have the second one close to the subject.
