Documenter of life, Karah Mew sets her second assignment for us and asks you to consider a photograph so precious, you may not have a second chance tomorrow to capture it. The assignment is a challenge set for the next seven days; a way to think differently about how you approach making your pictures. I'll be fascinated to see what you come up with, so email what you make to the show via the contact page. Supported by our Patron Extra Milers and MPB.com
