Long-exposure photographs present distinctive philosophical challenges. They do not quite look like things in motion. Experiences of such photos take time, but not in a way that mimics the time of the motion depicted. In fact, it would not be off base to worry that these photos fail, strictly speaking, to depict motion or things-in-time. And if they fail to depict motion, then it is an interesting question what, if anything, they succeed in depicting. These timeless traces of temporal patterns are thus a challenge to how we understand pictures. In addition to being representations, however, such photographs are recordings. They witlessly register aspects of scenes in a manner that can be replayed. The following shows that recording is a valuable and neglected tool for investigating representational practices. Aspects of what photos record also figure in their representational contents, and this provides a way of approaching the photography of events in time. This article proceeds by framing, and then answering, three questions. First, what do photos record about temporal patterns? Second, which aspects of such recordings also show up in photos’ representational contents? And third, do these pictures depict, rather than merely represent, such temporal patterns?

The nature of representation is a central topic in philosophy. This is the first book to connect problems with understanding representational artifacts, like pictures, diagrams, and inscriptions, to the philosophies of science, mind, and art. Can images be a source of knowledge? Are images merely conventional signs, like words? What is the relationship between the observer and the observed? In this clear and stimulating introduction to the problem John V. Kulvicki explores these questions and more. He discusses: the nature of pictorial experience and "seeing in" recognition, resemblance, pretense, and structural theories of depiction images as aids to scientific discovery and understanding mental imagery and the nature of perceptual content photographs as visual prostheses. In so doing he assesses central problems in the philosophy of images, such as how objects we make come to represent other things, and how we distinguish kinds of representation - pictures, diagrams, graphs - from one another. Essential reading for students and professional philosophers alike, the book also contains chapter summaries, annotated further reading, and a glossary.

Problems concerning scientists’ uses of representations have received quite a bit of attention recently. The focus has been on how such representations get their contents and on just what those contents are. Less attention has been paid to what makes certain kinds of scientific representations different from one another and thus well suited to this or that epistemic end. This article considers the latter question with particular focus on the distinction between images and graphs on the one hand and descriptions and related representations on the other. *Received January 2008; revised September 2009. †To contact the author, please write to: Department of Philosophy, Dartmouth College, Hanover, NH 03755; e‐mail: [email protected].

Analog representation is often cast in terms of an engineering distinction between smooth and discrete systems. The engineering notion cuts across interesting representational categories, however, so it is poorly suited to thinking about kinds of representation. This paper suggests that analog representations support a pattern of interaction, specifically open-ended searches for content across levels of abstraction. They support the pattern by sharing a structure with what they represent. Continuous systems that satisfy the engineering notion are exemplars of this kind because they are uninterpretable unless they are structure-preserving. Analog representations, so understood, include pictures, images, diagrams, and most graphs. This conception of analogicity also fits well with a line of thought about what makes perceptual states distinctive: they satisfy a “parts principle”

There are undeniably many ways of depicting things, but it is unclear what the diversity of depictive representational systems consists in. What is a way of depicting something, and how many ways of depicting things are there? Pictorial diversity starts to seem interesting and confusing when one tries to fix a picture's content while varying its surface features, or vice versa. This chapter seeks to explain what is at issue in discussing pictorial diversity and to introduce two tools for understanding it: the notions of syntactic competition and semantic competition. The fact that pictures compete neither syntactically nor semantically places important constraints on picture interpretation.
