Do you think being able to copy a picture is a talent, or do you need to come up with a image yourself to be talented?

I have always been good in art. When a teacher asks me to draw a person, in a realistic way, it looks like crap. Now if she gave me a photograph of a person, I could probably draw it very accuratley. I like to draw what I see, not think up things in my head and transfer them to paper. My dad once told me I am not talented because I can’t draw from my imagination. I think it is more rare and good to be a artist on your own. What is your opinion, do you think it is a talent to be able to replicate things onto paper?
