I don't read blogs regularly, but one blog I can recommend for Paris addresses and beautiful, unconventional photography is Le Journal. Most Paris lifestyle blogs feature the usual suspects: Carette, Holybelly, Clint, etc., all very nice, if you like being around Anglophones. Kumiko Nakagawa highlights favorites among longtime Paris residents, such as Musée Carnavalet, Jardin Anne-Frank, or Les Arts Décoratifs. The photos are natural and unassuming, and I appreciate her taste in shops (Ecua-Andino, Jean Paul Gardil) and street style subjects (vintage clothes on actual old people).
