I'm a fan of Salgado's work, but in my humble opinion Genesis does not have the same caliber of his previous works.
Not only that his RAW files are badly processed, but more importantly he started this project when digital camera did not have the dynamic range of today's cameras, and most importantly he shot with Canon, which until today lags far behind Nikon and Pentax in DR capability.
If you compare Genesis with his other works, you can clearly see the difference. While I'm no fan of film vs. digital debate, in this case Salgado should have stuck to using film, because his whole style was based on the capability of Trix -- changing horse in the middle of the river, with his last important project was a mistake. Unless of course some other wonder software comes around and his Genesis work is processed again and sold in a new edition - more money for everyone.
