FLASH

The pros of using flash are; it adds light to dim situations, it takes away shadow, it freezes time and it eliminates blurs. The cons are; it could disturb your subject, it creates ugly lighting situations, leaves really shiny bright spots called hot spots, it leaves the background very dark, and it leaves red eye. Flash would be a good idea when you want a snapshot or when its really dark. Its usually not a good idea when your in good sunlight, or when you want to take a picture of lights or scenery at night. This picture is better without flash because the flash is a much brighter light and if you used the flash, then it would eliminate all of the colors and uniqueness in the christmas lights.
