I am looking for a filter to put over my Yongnuo flashes to block visible light and pass IR wavelengths. I spent 2 hours googling IR flash and found only entire flash units, lens filters and technical papers on IR. Just want some plastic to put over the flash head.

Strips of unexposed, developed colour film will block visislbe light and allow IR through. If you have a local camera store, they'll have chunks of it lying around for the taking.

I looked a Kolari and have to wonder if it will fit a Yongnuo YN 685 flash.

Camtraptions shipping is as expensive as the filters. $18.95 standard or $65 express.

I found a 720 NM filter on Ebay. 82 mm for $25. I know the thing is lousy but on the flash that will not matter.
