Re: Thanks for the idea

I have got a few of my wife's beads.The problem with the reflective hemisphere is that set up acts a a more powerful ring flash as the hot spot is ring shaped as was the fat reflective strip, but more so. It works much better with the MPE at x1 and x2 as the closer working distance seems to blur the ring highlight more than with the 100mm macro. I have a different arrangement with using a Fresnel sort of reflector baffle that reduces the centre more than the outside. This has a harsh transition so I have used three layers of the sandwich bag as more diffusion, This is not bad.as the hot spot is softened. I will post some pictures as soon as I have copied them off the card. It is all pretty good without shiny subjects. It is shiny ones like beads that are tricky, as usual
