“Pissarro was the subtlest of the leading Impressionists, devising ways of giving distinctive presence to each part of a painting, by, for example, defining the edges of objects with the paint that surrounded them.
“For him, an edge was a place where paint didn’t stop but only changed color.”Peter Schjeldahl, “My Struggle with Cézanne“, The New Yorker 21 June 2021
Depicting an edge using what’s around it is not something I’ve consciously thought about, other than when using ’empty’ negative space. Another
complication challenge to embrace.
