Alexandra,

When I have a little more time I will give you the instructions.

I guess I owe the explanation:

On a tripod with a 70mm to 200mm lens
That is 130mm difference so calculate the half way point, 65mm
Add the 65mm to the 70mm = 135mm
So now you have your three stops, 70mm, 135mm & 200mm
Start at 70mm for 5 sec, then slowly zoom to 135mm over 5 sec, hold for 5 sec and zoom to 200mm for 5 sec and hold for 5 sec.
I was at F32, 30 and 100 ISO

Then look to see if you got it and try again. I did about 10 shots.

Steller shot John! Another good way to use this technique is with fireworks. Have fun and push the envelope!!! :)
