It's not that I needed another ringflash device, but Tesco's had a special offer on stainless steel pudding bowls ...

Very thin metal, so it did not take long to grind out the openings. So thin, in fact, that I can firmly screw two filter rings together with the bowl between. And it's highly polished on the inside.

Here's a sample. First shot is late afternoon sunlight (yes, the sun came back) ...

Second shot is sun-balanced ringflash ...

Now you can see what was hiding in the shadows.
