Saturday's Daily Yomiuri had an interesting feature article on Japanese photographer Shinichiro Kobayashi who is famous for documenting abandoned buildings, mines, theme parks, schools and hospitals within Japan over the past 20 years. His books include Ruins and Deathtopia.
Ruin Japan is a site by another Japanese photographer continuing Kobayashi's explorations of abandoned urban spaces (via Easterwood).
Melissa Lyttle is a photojournalist based in South Florida. She also has a fondness for Polaroid's i-zone instant camera (via netdiver).
Zave Smith has a beautiful flash portfolio, specialising in portraiture and still life (via netdiver).
