Artist Analivia Cordeiro shares the process behind her father, Waldemar Cordeiro's groundbreaking computer art from the 1970s:
...
“Waldemar Cordeiro was a Latin American pioneer of electronic art, or computer-art as it was called in the 1970´s. The images of his computer-art production are taken from photographs, like this work based on an image of a demonstration in São Paulo, Brazil.
...
The first step in Cordeiro’s process was the digitalization of the photo, done manually because scanners didn’t exist at that time. The photo was printed using an offset technique (photo 2), and a grid was placed on top of this image. Each square of the grid was numbered manually with a value between 1 and 7, indicating the image’s degree of darkness (photo 3). These numerical values were transcribed to punched cards, each line of the image corresponding to one punched card.
...
The second step was printing using letters, chosen by the artist (photo 4) to recreate the black and white levels of the original photo. Using an IBM 360/44 computer, the process of printing each image took approximately 5 hours. Finally, to produce this specific image, “Gente Ampli*2 (People Ampli*2),” Cordeiro enlarged the digitized image using mathematical procedures that are still in use today.”
