Inez van Lamsweerde & Vinoodh Matadin have quietly put together a coffee table book of unforgettable photographs spanning the couple's 26-year career and romantic relationship. Pretty Much Everything (Taschen) will pretty much cost you an arm and a leg with a price tag of $700 for the 342-page limited edition tome, which includes contributions by Olivier Zahm, Penny Martin, Michael Bracewell and Bruce Sterling. If that seems worth it, Amazon appears to have two copies available to get in time for Christmas. If not, Style.com has a slideshow of 15 of their most memorable photographs, with insightful commentary from Inez and Vindoodh about their shoots and subjects like Kate Moss (the above photo is their favorite they've taken of her). Meenal Mistry also did an in-depth interview with the couple for Style.com's "Image Makers" series. Click through for the most interesting tidbits about them, putting flowers in Bill Murray's hair, their favorite models, their stance on under-18 models and making Lady Gaga cry.

In the world of fashion there is a small yet consistent collection of photographers who get the majority of work for major publications and brands. In fact, many of them seem to have quite the monopoly on the fashion world. Legends like Richard Avedon and Irving Penn continued to work prolifically up until the time they passed away, and that seems to be what is so great about being behind the camera instead of in front of it. Top photographers are given the chance to work for years in an industry where most figures are in one day and out the next. But how do we differentiate one top photographer from another? We'll show you what to look for from visual style, what publications they regularly appear in, as well as recent ongoing collaborations with brands and models of some of the top working fashion photographers of today.
