Fireworks over the Matterhorn

Fireworks over the Matterhorn at Disneyland

I love looking at pictures of the fireworks at Disneyland, but I am still working on getting some that I like just right.  More practice!
This one was shot with a Nikon D800 at 1/40, f/2.8, ISO 4000 using a 200mm lens set at 78mm.
If I could do this over again I would change a few things.  1) use a filter and set the time for a little longer, say 2 to 10 seconds, 2) lower the ISO setting to 200 or so and 3) change the f-stop up to 14 or so.
I had just finished taking pictures of Fantasmic so those were the settings I was using.
