Old School OHP

acetates 1

 

I’ve been posting about the field trips I went on recently with colleagues from Swansea University’s FIRE Lab, walking the path of the River Tawe and making cyanotypes along the way. Mostly we made photograms – photographic prints made directly from found objects placed on the paper. But we also took some time out to draw onto Over Head Projector (OHP) acetates with various drawing materials to make transparencies to expose back at Swansea Print Workshop‘s Ultraviolet Unit. Younger readers might not know what an Overhead Projector is. It’s proper old school. These days we’d use a Powerpoint presentation, a laptop and a projector. Back in the day, we drew or printed our material onto an OHP acetate and it was projected onto a screen from an Over Head Projector.

The picture shows the transparencies on the UV Unit, ready to be exposed.
