Visual
The black and white emphasises the different races and the repetition of the physical bar standing between the people, and the rest of the bus, shows the segregation and categorises them individually. The photograph demonstrates the rule of third as it has vertical and horizontal lines. It also shows signs of Ansel Adams zone system, the brightest point being the white bars.
Conceptual
The idea that America in the 1920s wasn’t a great life for everyone , and racism was a apart of everyday life, revealing the cruel reality of the ‘American Dream’.
Technical
The photo has natural daylight as Robert Frank was a documentary photographer. The photo was taken on the streets so has no artificial lighting. He used a fast shutter speed as the photo is very sharp and not blurred so if the bus was moving at the time he captured all the detail.
Contextual
The 1920’s was a time of racism and prejudice and it was uncommon for photographers to tackle the issue of racism at the time.
