estrach lives in Croix near Lille in the North in France.
This website shows some estrachtions which are selections of his pictural abstract photographs posted on his tumblr page (estrach.tumblr.com).
This photoblog has an experimental dimension : anywhere in the town the square is looking for all the compositions made possible by human activities, chance, time and weather.
