Work gets in the way.
You go to the Sistine Chapel and you look at the conservation as well as the artwork. You go, 'the varnish is a bit glossy'. As part of Science Week, Mr Wise discussed his part in the 1997 analysis and restoration of Waterlilies by the National Gallery of Australia. The NGA repaired water damage the painting had sustained some time in its 80-year history, possibly even while in the artist's studio. Moisture had seeped up through the timber frame and had led to cracking of the paint along one edge of the picture.
