I'm saddened to hear of the controversy of the wolf, and/or that the image is sullied. I liked the image immensely upon first seeing it had won the BBC WPOY contest. Noted that it had been captured in the Spanish wilds by an IR triggering array and a Hasselblad, if I recall correctly. Such images are indeed possible with seldom-seem and rare creatures, and make a good case for the viability of MF film cameras even today.

Having myself successfully captured wildlife remotes of a wild mountain lion I'd prospected and attempted to call to the camera for many months beforehand, I can state with some authority that a subject-triggered remote is sometimes the only way to get an unobstructed view. It's not nearly as simple a project as the first-time poster above suggests.
