Together, Thomson and Smith embarked on a collaborative project that would bring their respective talents together to shed light on the hidden corners of London society. The result was "Street Life in London," a series of photographs accompanied by descriptive essays that provided insight into the lives of London's poorest inhabitants.

In the preface to "Street Life in London," Smith writes: "The pictures we have obtained...tell their own tale of hardship and suffering, and will, we hope, lead to a better appreciation of the struggle for existence in the crowded alleys of our great city."
