The photogram process was used in early photography, is it a camera-less technique.
The object is placed directly onto light sensitive paper and exposed to light (I use my enlarger), then developed in the darkroom – just like traditional prints. However unlike traditional darkroom prints there is no negative.
The object creates its own image. Each print is unique.
The process results in areas where the object has been placed remaining white – in effect the object is a mask – and areas that received light (ie the negative spaces where nothing is placed) become black.
Objects of different qualities produce different results: objects like feathers let more light through than solid objects such as a stone. Plants work well with stems giving solid areas and petals letting some light through so giving a grey more delicate shape. I particularly enjoy making photograms with seaweeds.
Some reproductions of these photogram are available as cards here.
