another beer can flash diffuser

Tecates are delicious. It's best to choose a delicious brand of beer for your beer can flash diffuser. Too bad Negro Modelo doesn't come in these big cans.

Yes. Crumby decided on a big can for his diffuser. That's because the macro lens we are now considering is fairly long. Also it's 1:1 at about 9" beyond the lens. But also because the big cans hold more beer. Crumby decided to guzzle up two big cans in case he screwed up the first can during the manufacturing process.

This diffuser is fairly easy. Cut off both ends of your beer can after you have drunk up all the delicious beer. Use electric tape and styrofoam bowl to fit one end snug onto the flash head. Cut the other end at an angle so that it will point at your bug or whatever at the prescribed 1:1 distance. Get your styrofoam bowl. Staple a rubber band rope onto the styrofoam bowl. Loop the rubber band rope around your flash head.

This system seems to work pretty good for reducing the "specularity".

By the way, the picture is taken using the canon 10-22 with pop up flash. The diffuser used on the pop up flash is a pollen or dust mask that are available almost everywhere. The pollen mask already has rubber bands ready to be attached to your camera under the OVF. How handy is that? And the pollen mask greatly retards, but does not entirely elimnate, the "specularity".
