The response to Prison Photography so far has been "thoughtful and engaging," according to Brook. Still, he's aware that blogging has its limits: "I'm very comfortable behind my desk, writing and churning out ideas on my blog. I could do it indefinitely, but I realised that not all people consume information in the same ways." So how would you take a blog and give it material form? First, Brook launched a crowdfunded road trip across America, to visit with photographers he'd featured on his blog. And next, starting on February 17, he's helping to organize an exhibition of prison-related photography entitled Cruel and Unusual, which will be shown at Noorderlicht Photo Gallery in Groningen, the Netherlands.
