There are typically two extremes to the street photography approach. One is being completely stealthy and ninja-like to capture spontaneous, unposed, and original moments happening on the streets, as if the photographer is merely observing without active interaction (eg Henri Cartier-Bresson). This is opposed to the straight-in-the-face, direct, confrontational approach (eg Bruce Gilden). Giovanni Aiello found himself identifying with the former approach in street photography, which he has been doing on the northeastern streets of Italy.
Since the University days of studying psychology, Giovanni Aiello has always been curious and fascinated by human nature and emotions. Therefore it was not a coincidence that he took up street photography to document everyday life around him, while including emotions in his street photographs. Giovanni claimed his photography has no journalistic intent or educational purpose, and instead he was merely observing the people he encountered on the street and tried to capture the feelings associated with the scenes he framed. He further acknowledged that, while images ultimately are shown in just two-dimensional format, human feelings however have infinite dimensions.
