I found and followed this link for instructions on making cheap and cheerful collapsible reflectors for my strobes: http://super.nova.org/DPR/DIY01/
The cost about $5 each and take about 10 minutes to make. In a word – recommended.
The word is that these produce nice soft lighting at very low cost, are quick to makeas they only involve minimal measuring and cutting, plus are stapled together (I made 2 in less than 30 minutes), and best of all are flat and flexible to put into a gear bag, occupying almost zero space.
Update – Having now tested them, they produce nice soft light, far better than from using a plastic diffuser on the flash head. Much cheaper too – do my international readers know that a Stofen OmniBounce costs 40 bucks in the Land of Oz – and that’s with dollar parity with the USA…
So, I am changing my rating to ABSOLUTELY RECOMMENDED.
I now need to make 2 more – I have the velcro and interfacing stiffener, plus two more white foam sheets, but the local craft shop has no black foam for another 10 days, sigh. I now need to sort out my stand heads…
