Fireworks and the 7th Earth

HSBC Celebration of Light is the largest firework competition in the world. Spain, Canada, and China join the race in 2007. The firework begins at 10 PM rain or shine.
Last time I took pictures about the firework on Canada Day. I was very silly that I forgot to use black-card. I knew the technique before I went to Vancouver. But I omitted it. I was so lucky that some pictures were not very bad. When PoYang who took attention to the EXIF saw the pictures on Flickr, he gave me some advice and taught me how to use black-card.

I tried to use black-card in order to take fireworks. I found it was very useful and helpful. In case of the black-card, you could catch the firework easily. Workings were better than last time and so amazing. If you don’t wind up regretting, don’t leave the black-card out.

You can make the black-card which is non-reflection card with non-reflection materials. Good luck. ^_^
