>You aren't holding it if you can't draw from it.

That doesn't sound plausible.

In my personal case, I can maintain a clear image but be unable to translate it accurately to paper or to another medium (electronic or not) since it involves skill. The fidelity I am able to attain has improved as my skill has improved, and I can clearly see the frustrating differences between the image in my mind and what I then drew without yet being able to remedy it. If the proposition were correct neither of these things would be possible.
