I had my $10 op-shop Ricoh rangefinder, weighty in my pocket, way back in 2001. The guard at the NGA let me take this photo without a flash. I did and put the camera away and enjoyed the rest of the gallery without thinking of taking any more photos. If there'd been a lot of people around, I wouldn't have done so but we seemed to be the only ones in the surrealism room of the National Gallery one chilly July Sunday morning.
Nowadays galleries are overrun by tourists with non-stop shutters and hipsters with fancy photophones ("fotofone" - have I coined a new word or overheard that somewhere?).
