I’m a big fan of Bert Monroy’s Pixel Perfect – a weekly Photoshop video podcast. In a break from the usual format, this week Bert talks to photographer Stephen Johnson about the impact of digital photography.

The main area of discussion in this show revolves around what constitutes a ‘photograph’. Stephen believes that as soon as you alter a photo in any way it ceases to be a photograph, but becomes a form of digital artwork. An equally valid, but completely different art form.

The whole show is included below, or you can download it in different formats from the Revision3 web site.
