I proudly posted the results of my beauty dish below on the Strobist thread and some folks who clearly know more about the quality of light than I do ask some questions… First they said well show me some pictures of how the light spread out on the wall? So I took some pictures… I wasn’t real happy and the results shown here.
So I listened to what they had to say and I made adjustments… I changed the CD cover that was holding my convex mirror to one that was about 2 1/2 inches longer. The difference was striking. Just not good. The new version of the mirror holder made the center circle more pronounced.
The answer to all of this was to create and adjustable mirror mount. It’s funny because that’s what I had on the old plastic dish I tried a while back – not that I adjusted it but it was adjustable. So I pulled it off the old one and move it to the new better dish and flash mount. The new old mirror was just mounted on the bolts through the same type of door guard with a CD. Once I moved it to the new dish it was just a matter of moving it in and out until I found the sweet spot for my dish. turned out to be way closer than I would have guessed – only about an inch from the flash. But the result looks way better – no dead spot at all. Here it is.
So the bottom line with the beauty dish – never mind what I said the previous post… there should be no dead spot and who ever told me that was an idiot – the light should be smooth as eggs!
