Ok I know I promised to keep the show length down but I had so much competitiony goodness to tell you about this week that I kinda over-ran my 30 minutes again. Sorry! But on the bright side this week you get the chance to win a ColorVision Spyder 2 PRO in our first ever PhotoWalkthrough Challenge! The topic of the challenge is "Colour" and all you have to do to win is take a photo inspired by that topic, upload it to Flickr and tag it with "pwchallenge1".

On today's show we convert Michelle's image to a gradient mapped sepia tone and add even more grunge using those Nagel brushes. And at the end I finish up by quickly showing you an image by Agnes Liu that does a similar job of distressing a photo. Inspiring stuff!
