Sometimes a dog is copacetic about having his picture taken; when he’s playing and doesn’t notice, when he’s fast asleep and looking angelic or when you let him hold his favorite tennis ball while you focus and shoot.
At other times, he may not like the idea so much. He might cooperate anyway…
Or decide to opt out.
Happily, with digital photos, since you get to delete the losers, you can keep shooting until you have just the shot that pleases you, one in which the dog has not run out of the picture and where his personality shines. Good boy, Flash.
