Sean Tucker sets his third challenge for the next seven days asking us to think like designers. I talk to Sean about a style of photography he is known for when he photographs on the streets and like the last challenge he set, this has a gentle observational tone which will suit photographers of all levels and interests. It's great to see the pictures you have been making from the assignments set so far, so please keep sending your photographs for inclusion on today's show page. Email through the SHOW PAGE.
