If the National Media Museum isn't directly interested they might be able to suggest somewhere that would be:

(PS: I had a similar problem when my father passed away. He had a substantial collection of wild flower photographs. The quality wasn't good enough - or the species rare enough - to make his photographs valuable to organisations like the RHS, so I ended up giving them to a drinking partner of his, who shared his interest in wild flowers)
