Back to the OP's question, yes I do sell my work and in a number of ways although I've scaled it back in recent years because of very infrequent darkroom access while living abroad (outside the UK). I do some commercial work (non analog) but plan to resume traditional prints ales when I get a new darkroom setup (it may be temporary).

I sell through workshops, Exhibitions and Galleries, plus a few on-line although that side could be vastly improved. Apart from sales I've also had support & sponsorship from Arts bodies and suppliers and I think that support for production is extremely important - if the work merits it.
