I find the situation highlighted in Katherine Tyrrell's blog post on this year's Derwent Art Prize highly disappointing. Essentially, the winning piece was a straight copy of a photograph in the public domain. There are no copyright issues, but the artist essentially used someone else's design, contributing only technique. The competition rules state "no copies", yet this is clearly a copy.
Although Derwent (the pencil people and sponsors of the prize) do not judge the competition, this still reflects badly on them if they do not react to an unfairly judged competition in their name.
