As a participant of the project, you should think carefully about where to place your pinhole camera.
Because of to the long exposure time, moving objects are not visible on the images. This restricts the choice of motifs. However, this restriction can also be used as a stylistic device
The main motif of the pictures (bicycle handlebars, bicycle with spokes) is sharp. Everything else is blurred or only visible as a veil because of the exposure time of several weeks. Here and there you can see the outlines of a house. In some pictures you can even see traces of the sun. A kind of depth of field brings tension into the picture and lets the actual subject protrude.
