Animals are not aware of when you need to take a good photo. They may stop for a few moments in curiosity to try to figure out what you're doing, but other than that they have no concept of helping you get a good picture. I thin I may be getting slightly better at it though, because I'm learning what is and isn't possible with animals. Take this cow for example, this is the most recent picture I've made of an animal. It probably only stopped for a minute or so to get this picture. I even kept making clicking noises to keep it focused on me for a few moments while I got the picture.
Not all animals are like cows though, and respond to noises. The majority of turtles I've come across love to crawl back into their shells at the sight of a person, so I tried to zoom as closely as I could while remaining hidden to get this shot. He caught me but thankfully chose to freeze, and only stare at me instead of running.
There was also this frog. They don't mind running from people, and can't be stopped with noise. I was thankful he stopped for a few moments so I could get this picture really quick before he got away.
Lastly there is my dog, who is probably the worst picture taker I've come across. She has no idea of what being still or even calm means. When I have her out for a walk it is just chaos. I've been able to get better pictures of her as I got more experienced with the camera, but this one just sort of came out of nowhere. I thought I caught her being still, but then she came running at me. Thankfully my shutter speed was fast enough to capture her.
