Rapid focusing and composition takes practice. Getting good opportunities to hone these skills in rapidly-changing conditions is important, if you want to capture that awesome shot of, say, wolves bringing down a deer. I don’t have any wolves (or deer), but I do have Rex (a.k.a. the Rexaroo. my friend Bekka Brodie‘s dog). This fast little guy provides a great opportunity to practice these skills, and makes an engaging and photogenic subject in his own right. Check out the shots I got of him yesterday afternoon!
Here Rex seems to sense impending doom.
