This year at Greenbelt we're inviting festivalgoers to bring along a print of a photograph that they have taken for an open exhibition in the Hub.

Then at the end of the Festival we'll host a special photo flash swap event, when everyone who has work on display there can exchange it for one of the other prints in the show.

How it works:

The flash swap is open to all ages and abilities.

It's one print per person, so choose an image that you're really pleased with.

Mounted prints would be great, as that'll make them easier to display, but unmounted work is acceptable.

Prints for the show must be delivered to the Hub between 4 and 6pm on the Friday, and a team of volunteers will assemble the exhibition.

Everyone who leaves a print will register and be assigned a number [we'll keep a list]

We'll have some forms, available on the Hub info desk and also here for folks to fill in any info about themselves and their photo.

At 6pm on the Monday we'll host the flash swap - there'll be refreshments and a short and pithy address...

At the swap, everyone registered will be given a sticker with their number on it, and at the given signal you'll be invited to go put your sticker on the print that you would most like to take away with you.

Once it's all done and dusted, everyone can take their chosen print and leave...
