Question Very strange effects in the darkness under the arch. Is that loss of varnish on the painting or an imaging problem? --MichaelMaggs13:45, 7 July 2007 (UTC)[reply]
Info It doesn't look like JPEG artifacts, but it's entirely possible that the image was scanned/photographed and then levels-adjusted, causing the two-tone dark areas. It's also possible that it's the varnish thing that you mention. As I haven't seen the original painting (just countless reproductions), I can't say for sure. grendel|khan13:32, 8 July 2007 (UTC)[reply]
