Here is a bit of text about Positive.Negative:
--
positive.negative is a strategic intervention into the existing gallery space. A dynamic object in two parts consisting of frame and infill, remakes the space into various scenarios for possible exhibitions.
The mutability of the gallery opens up unexpected possibilities to rethink conventions of white-cube-art-spaces as a static framework. Positive.negative densely probes new forms of presenting photography.
