We recognize that you may have your own favorite filter and shouldn’t have to use c-47’s to hold them to your barndoors. Since their are tons of filters, it isn’t practical for us to make them all, at least at this point, but that shouldn’t stop you from being able to make your own. All you really need is the holder, your filter of choice, some scissors and a little superglue.  So, we are making the filter holder available to you.
