We develop a general Shockley-Ramo-type framework to describe spatial patterns of photocurrent response in gapless materials. Our approach helps to understand the striking features of the observed patterns, such as the directional effect and the global character of photoresponse. We illustrate this approach by examining specific examples, and show that the photoresponse patterns can serve as a powerful tool to extract information about symmetry breaking, inhomogeneity, chirality, and other local characteristics of the system. Short response times, originating from the nonlocality, make photocurrent uniquely sensitive to the charge and spin dynamics of the system.
