Dulwich Picture Gallery has a great collection and puts on some wonderful temporary exhibitions. However, I remember the days when the staff and volunteers were friendly and welcoming, which is no longer the case. The invigilators in the temporary exhibition galleries have very little consideration for visitors (and I've experienced insolence from them) and heaven help you if you step over the lines on the floor in the main galleries, wanting to take a close look at the brushstrokes in paintings that are glazed and, therefore, unlikely to be harmed by you getting close to them. Oh no, step over the line for a close look and you are pounced upon and told quite firmly to keep behind the line. Thank goodness there are other galleries where it isn't a strict requirement to keep so far from the paintings that you can't examine the artist's mark making.
