Paul, I know you posted how you have your flash diffused, but I don't get it! could you post a photo of it? I'm only at IKEA levels in terms of assembly manuals!




OK.
The first move is the protective foam packaging that covers the edge of shower screens which you should be able to get from a hardware store:

Then from a polystyrene party plate cut two C shaped pieces, and also two C shaped pieces from a plastic supermarket milk bottle (the opaque bottles) but tidy them up before use of course, to the size just large enough to cover the tubes areas of the ring flash:

Once all that is done, attach the shower screen foam around the outside of the ring flash, and once that is held in place by plenty of strong adhesuve tape, and push the 4 pieces of cut outs underneath this foam. More cutouts can be used if the diffusion is not enough:

Hope that helps.
