I really like the concept behind Animal Ark and Sartore's work. I get the idea behind using plain backgrounds to let the animals stand out with their own features. And that photos of some of these animals can be really hard to take. But some of them are the animal facing away or only partially in the frame or otherwise not fully visible and it seems like, not "bad" photography, but like better images could have been chosen. I picked the book up mostly for the photos but I actually found the facts and info tidbits included with each photo and how the book was sectioned into how many (estimated) of each species is left more useful.
