I did an enhancement for somebody which really brought out the detail of the original and added my own artistic license. There is talk from the owners and its fans that it should be entered in to a competition. Am I to assume that I will not be entitled to any creditable recognition for this work should it win?The person who technically has the copyright of the original piece will in that situation only have given you limited rights to alter the piece they still retain the copyright to the original and any adapted or derivative work unless there is an explicit legally binding agreement otherwise.
i think it would be a bit naughty if it means you added your details electronically to it
