Talk:Waldemar Cordeiro

I changed "derived from an image" to "derivatives of an image". The Portuguese title of Cordeiro's work is "derivadas de uma imagem" (see https://www.artbasel.com/catalog/artwork/60794/Waldemar-Cordeiro-Derivadas-de-uma-imagem). "Derivadas" here means "derivative" (as in Calculus), since Cordeiro took the derivative of the image to produce another image. — Preceding unsigned comment added by 2001:980:8770:1:1059:19E4:3CDA:8380 (talk) 18:28, 31 August 2020 (UTC)
