YOSHIYUKI, Kohei. Secret photography – This is infrared photography!

(Tokyo): Sunday, Inc., 1981.  First edition.  Paperback original.  Unpaginated.  Neat little volume with a selection of images in which the photographer acts as voyeur but also turns his camera on other voyeurs.  Illustrated throughout with both colour and black and white images.  A very good copy in card covers with dust jacket.  Red lettering at the spine, lightly faded.
