Series 191103, 01-11, 2003: 11 works. Starting from a section of 9 x 9 pinhole structure elements 3.8.14 D 7 I, 1973, reduced the number of pixels per inch (ppi) in the reproduction of the original from picture to picture while maintaining constant dimensions, each reduction approximately the half of the initial 1200 until left with 1 pixel per inch. The absolute number of pixels involved is thereby reduced from 5669 x 5669 = 32,137,561 to 5 x 5 = 25 pixels.
