Personally, I was unconvinced by using foamboard to mount the images. In the new Hostry, on the Cathedral's own display stands, it was quite obviously the right decision. The pictures look stunning and, again, I have to admit, that this year's exhibition is much better than in the recent past: the standard of pictures is much higher, mounting is more consistent and the new venue is excellent.
SO, make sure you see it in the coming week and half before it comes down.
