Dogs each have their own head tilting pattern, ranging from slight to extreme. Cats tend to twist their heads at an odd upside down angle, usually just before pouncing on something or running away (oh, a bug--head tilt--pounce).
I tend to like a middle of the road head tilt. I use a variety of sounds and noise makers to get the tilt, but each photographer has their own way of getting a dog to offer the tilt. Sometimes I will ask a client if there is a special word that might get the head to turn sideways. In our house SQUIRREL is that word. We can't even spell it. Sometimes TREAT does it as well.
I am sure you will see many more tilting heads in the blog circle today. So why not head (no pun intended) there now. Start with Linda Perdue of VP Shoots Photography serving Tampa, Florida and surrounding areas. Have a great weekend!
