The camera or the end of the direction vector is inside the bounding
sphere of the fractal. Modify your camera statement to:

camera { location -5*z angle 30 }

and it works. Also, precision 2000 is overkill, I have rarely needed
more than 100. Be warned that at iteration levels above 6 you should
expect a lot of fractal dust. Lastly, I suggest giving the julia a
no_shadow statement for test renders because you can make out the
shape better this way and it's also faster.

Enjoy!

BTW have you been able to grasp how the different parameters, more
precisely the two vectors, affect the shape of the fractal?
