Tate Online Lectures with Photographers

The Tate Museum's website has an archive of past events. There are a

handful of photographers who have been interviewed, including Martin

Parr, Philip Lorca Dicorcia, Rineke Dijkstra, Sam Taylor-Wood, and a

few other artists who work in video and photography (like Fiona Tan

and Sharon Lockhart).

These talks don't necessarily give a good introduction to an artist's

work, however, if you already happen to be interested in a

partiuclarly artist, then these talks can provide more insight into

how he or she works.
