The photographer didn't get the copyrights exactly because he didn't "engineer the entire situation specifically for that outcome". If he did create the situation, he'd get the copyright.
> In an attempt to get a portrait of the monkeys' faces, Slater said he set the camera on a tripod with a large wide-angle lens attached, and set the camera's settings to optimize the chances of getting a facial close up, using predictive autofocus, motor drive, and a flashgun. Slater further stated that he set the camera's remote shutter trigger next to the camera and, while he held onto the tripod, the monkeys spent 30 minutes looking into the lens and playing with the camera gear, triggering the remote multiple times and capturing many photographs. The session ended when the "dominant male at times became over excited and eventually gave me a whack with his hand as he bounced off my back".
