Yeah I hate how quick and precise you have to be to get the special snapshot for some to get the 4 star shot. Like Jirachi for example. You have to be so fast on the first shot. It'll fly off, then right near the end portal it comes back and you need to hit it with specific items, and get it to do the pose. It's tough, but I've got it a few times. It's just challenging to do it and get a good shot before it automatically stops you and you're just wisked away.
