I found out, recently, that there's a Michael Kenna print sale / exhibition taking place at the Bosham Gallery in Bosham, West Sussex (PO18 8LS). As I'm a huge fan of his work, Mrs LD and I went to see it on Saturday. There's 40 photos displayed and, IMO, no weak spots amongst them.
The bad news is that the exhibition finishes on 31st August. The GOOD news is that from that date, the 40 prints will be replaced by 18 prints which haven't previously been released.
It's not the easiest place to get to (unless you live nearby) so I recommend giving the gallery a call to check the details (01243 681271) before heading there.
