Flickr member Dippold turned an old olive tree into a pinhole camera -
I have used the cavity of the olive tree as “camera obscura” of the photocamera.
It is equipped of a shutter. This shutter works with a method of carrucolas.
The camera has an internal device that support a 120mm film.
I have boxed in every slit of the trunk with filler.
