Before the actual exposures were made, a 

 sheet of white paper of the same size as en- 

 l^gmg paper, was placed on an enlarging 

 board. The different negatives, with the ex- 

 ception of the cloud negative shown on the 

 right, were thrown on it through an enlarg- 

 mg camera, and the relative sizes and 

 positions marked out. Numbers 1, 2, 3, 4, 5 

 and 6 are exposures of the same negative 

 through a ragged hole in a sheet of paper 

 held between the light from the lens of 

 camera and the paper on the enlarging board. 

 Numbers 7, 8, 9, and 10 are differently 

 focused views of the same aeroplane
