...is called "slow synchro flash"(or similar), whereby the flash is used to light up the subject first, and in conjunction, a slow shutter speed is used to give the background the correct exposure. Some cameras with "scene mode" have it. Some cameras can have the flash at the beginning or end the slow shutter sequence, giving different effects. A tripod is often necessary.
I just got myself a Canon Powershot TX1 a couple of months ago. Like most cameras, if you turn on the flashlight at night to shoot a wonderful glowing building, the resulting image will be "blackened". The flashlight must be turned off in order to capture the beautiful backglow of a lighted up building.
The problem is, if you turn off the flashlight, a person's face cannot be captured properly. However, if you turn on the flashlight, the person's face shows but the background building becomes "blackened". Is there anyway around this such that both the person's face and the background building at night may both be captured nicely?
Thanks for your help!
