What is the purpose of the Multi Firework scene?
The MULTI FIREWORK scene allows you to take two exposures and combine them on a single frame. Pressing the shutter button once locks the exposure and captures the first image. The image is saved and displayed in the background of the LCD monitor so that it can be used as a visual reference when composing the second image. Pressing the shutter button a second time captures the second image. The two images are then combined and saved to the memory card. After the combined shot is saved, the first image is again displayed in the background of the LCD monitor, where it can be used to create another multiple-exposure shot.
