I recently visited the SF MOMA; I didn’t want to miss the Richard Serra Drawing retrospective. After the visit we went to the rooftop garden, there is a coffee bar there and a few modern sculptures. These pictures are from that visit, they were shot with a telephone camera and I didn’t expect to find such a good pictures.
In the first pic the low winter sun rays cast long shadows as mine. In the second one, the sculpture folds are perfect to play hide and seek. In both, the glass surfaces around the patio reflect walls which otherwise would be out of the picture.
