When I see a mirror, my instinct isn’t usually to point my camera at it. But this was an exception. I was on the upper viewing platform of London’s Tate Modern gallery, with the iconic St Paul’s Cathedral gloriously in shot.

These similar photographs turned out very differently. Above, I’m (unfortunately) in full view, while the couple perched behind point at the view, which has been dazzled out of existence.

Just seconds later and a drastic dialling down of exposure, the three of us have become silhouettes, and St Paul’s, a slither of the Millennium Bridge and other buildings are visible.

These are not strictly speaking selfies. But which version do you favour? High key or silhouetted?
