“I was so dim,” says Greg Krum. It’s a Sunday afternoon, and Krum, best known around New York as retail director of the wonderfully quirky Shop at Cooper-Hewitt, is puttering around the sun-drenched kitchen of a renovated 1890s townhouse he shares with two roommates in Greenpoint, Brooklyn. He’s trying to recall the origins of his other career: that of a photographer about to mount his first solo show this May at New York’s Jen Bekman gallery. “Growing up, I was always attracted to making art, but I didn’t think I could do it because I couldn’t draw. I was like, ‘Okay. That’s out.’ Then I finally realized it’s not about that. It’s about living a life of ideas.”
