Standing Fountains Is It Safe To Photograph Fountain Type Fireworks When Standing About 50 Feet Away From Them Or Closer?

Is it safe to photograph Fountain type fireworks when standing about 50 feet away from them or closer? - standing fountains

I have a Nikon D60 with a UV ... This Fourth of July, I make a lot of fireworks. Most of them are of the type Mabye Fontaine and some that are in the air, but with whom I stand too far. My concern is that since I was less than 50 feet of fireworks in most cases, you can damage the smoke and Debra differently than the camera? It is within easy walking distance of it?
