If a picture is worth 1000 words what's a medium quality scan worth?

This talk will discuss some of the practical and conceptual issues of working with images collections, looking at how face recognition and pattern matching can help put some order into collections whose scope is too large for an individual to hold in their consciousness. Scaling up means we need technological assistance to explore large collections else we are constrained by human attention spans and memory. Scholarship needs to develop or at least face up to these limitations.
