This is a photo I took of the Providence, Rhode Island Waterfire event recently, which the City sponsors on summer weekends. It's a fascinating event and a must-see if you are in the area. The fires are lit by boaters from their gondolas using a large torch. There is also music accompanying the spectacle.
It's always tricky photographing at night with glowing flames. I generally focus my lens on an obstacle that is in-between too dark and too light, so that neither the dark nor the light areas become under/over exposed, bearing in mind that much post-processing work in Photoshop would need to be done no matter what the outcome. I primarily used the dodge & burn tools to emphasize key parts of the photo, such as the buildings, bridge, the water, and the crowds.
Enjoy the scene and keep taking photos!
