I would venture to say that although it appears that the baby is right up on the croc the effect of a zoom lens brings foreground and background
closer... I notice he takes a couple steps back after feeding the croc - the baby was probably 6-7 feet away horizontally and about 5 - 6 ft up at
Steve's shoulder and head level.
Once again with the baby dancing on the ground the croc is blurred in the foreground and he is in focus in the background... so he is probably even
further away than in the first scene.
I swear people get all bent out of shape over the most trivial things - I wouldn't do it but then again I have no experience with these creatures
(children) or crocs for that matter...
Sure, Steve shoulda been holding Michael Jackson by the nap of the neck that close to the croc but face it - he's been doing this for years - he
knows what he's doing~
