His Urban Landscapes series exemplifies his fascination with the ‘modern city’ as well as his fluency in printmaking. His highly polished technique of rendering a ‘photographic’ view through print was one he first mastered in 1971. The complexities of many of his images, which utilise a vast number of colours and tonal modulations make the proofing process extremely time consuming but the result is one of acute observation and accuracy, exemplifying Estes’ mastery of the medium. Working from photographs has also allowed Estes to achieve an extra-sensory effect, producing highly organised compositions and views, which are meticulously planned before being printed.
