By purchasing a participation set, you receive a non-commercial right of use for the entire archive. When using pictures (FB, print media etc.) we ask for a reference to the author (name with picture number) and the project name The 7th Day. If you are the author (photographer) of a picture, you are allowed to use it commercially. In this case, we ask for a reference to the project The 7th Day / P. Zajfert.
