If you are interesting in pyrotechnics, then this tutorial is special for you!
At first, find some appropriate photo of the night sky and fireworks where we can demonstrate fireworks effect. I think the following photos will be great example. Open the first one picture, and open the second as a new layer. Then, use Free Transform Tool to change this fireworks picture to a suitable size and place.
After double click, change this layer blending to Screen, and add a Mask.
Change Opacity to 50%, and select Brush Tool to move the fireworks out the building.
Looks good. It's time to return the Opacity to 100%. Now, we have something like the following:
Looks better, isn't it? This is what I want. Have fun with this tutorial!
