Louvre Kerfuffle

Have restorers at Le Louvre made a pig's ear of Leonardo da Vinci's The Virgin and Child with Saint Anne? Two French art experts have quit Le Louvre's advisory committee over the restoration, which they claim has been over cleaned and is now too bright (title link). I tend to agree. The painting looks as though it needs an XnView gamma resetting to give depth to the dark areas. The child's shaded tummy seems to have vanished too. Another Brillo pad job. Groan!
