I've only been to a few small quilt shows, all the others have been LARGE shows and no ... I could not possibly have taken pictures of all of them even if I had wanted to.
At every show there are some quilts that simply don't interest me and I don't photograph them at all. Others I take multiple pictures of especially if some intricate detail is a key element or done especially well (quilting, appliqué, beading, 3D effects ... etc).
