We have one two more nights of the long Independence Day weekend. When the sun finally sets, break out your camera and sparklers for fun holiday shots. Since it will be very dark out, you will need to boost your ISO to avoid both camera shake and blur from subject movement. Try ISO 1600. For the photo here, I also added a flash on slow sync. This flash mode sends out a burst of light to freeze the subject but keeps the shutter open just a bit longer to capture the sparkler motion as well as some ambient light for an image with more depth. If you are unsure how to set your flash to slow sync mode, you can also try the automatic “nighttime” mode on your camera, denoted by a person + star or moon on the mode dial.
