I checked in with PhotoWorks, it looks like they are planning a photography biennial in Brighton this year. I will keep an eye out for more details but this will probably fall in October. It usually runs parallel with the Photo Fringe which is scheduled 6-30 Oct. If anyone is interested you can enter work for consideration for the Fringe event. More details here: https://photofringe.org/take-part/photo-fringe-2022-real-utopias.
It might be good to organise a study visit to Brighton to coincide with the biennial?
