Orpheus mosaic.
In December 2012, the Dallas Museum of Art returned to Turkey a fragment of a Roman mosaic known as the Orpheus mosaic. This mosaic is exhibited at the Haleplibahce Mosaic Museum, and it is a shame to see how it is lit. I often find the use of (led)spotlights disturbing, but here they really mess things up. It is impossible to take a decent picture (or enjoy the work) from in front, because of horrid reflections. The one picture of it in all its “glory” I had to perspective-control after taking it from about 60 degrees to the side, only then were these reflections out of the frame of my picture.
