The Queensland Guild has just had it's exhibition and unfortunately there was no photography. This was a shame because there was some nice work on display. I really question the non photography rule at exhibitions. If people are going to steal designs they will do it anyway.
There was a lot of work there which was stitched by the embroiderer but designed by someone else. These are commercially available works so I can't see that no photography should apply. For example, the following image is of a kit for sale from the Japanese Embroidery website. This design was in the exhibition but it was far better than the one on the website but I can't show you because of the photography ban.
For the original designs copyright still applies but being able to photograph the works means there would be a lot of cross fertilization of ideas. In my opinion we are all becoming too precious out these issues.
On a lighter note I was amused by the number of visitors who came to the exhibition armed with a magnifying glass. Now that really is looking at the detail.
