I'm not sure if I really like Allan Tannenbaum as a photographer. Photos of celebrities and 1970s-era New York tend to feel a little cliched to me, and his website looks more like an ad for a bad nightclub than a photographer's portfolio. He has a LinkedIn account, which I find cool, but I don't know if that can make up for poor web layout.
Having said, that, however, he took some really lovely images of John Lennon and Yoko Ono a few weeks before Lennon was murdered, and compiled a book of them about two years ago. I haven't seen the book, John and Yoko: A New York Love Story, but I did see some images from it, and they were quite lovely, so I figured I'd share them with you. My two favorites are below, and you can see the rest in Vanity Fair.
I'm not sure why, but I really love images of John and Yoko, and these are no exception. Although I think it's impossible to tell the truth about anyone or any relationship from a picture, almost all photographs of the couple are beautiful or interesting in some way. I like the two I've included here because the first is lovely and composed, and the second feels spontaneous and, to me, very happy.
