The club has about 70 members, with about 30 exhibiting this year.
As is always the case, members have different styles, techniques, artistic expression and subject preferences, so the mosaic wall promises to be one of variety and interest.
The other two walls in the back gallery are different again.
John says they've changed it up this year and members who choose can have their own piece of wall, one and a half metres wide, as high as they like, on which to exhibit their own work.
"They can use that how they choose to display as many images in as many sizes and formats as they like.
"So three quite different expressions this year," says John. "Hopefully with some real interest for the public."
On the two Saturdays of the exhibition there is a further attraction.
"We will have a room set up for taking people's portraits. Two of our very good portrait photographers will have the screens and the lighting, so we will be encouraging people from the markets to wander in, get your portrait taken, and if you're interested in getting a print you can follow it up with the photographer."
Selected images will be used on the club's Facebook page and website.
