ISO 50FLASH
ISO is a way to pop out the lights around you to a level that makes it easier for you to see them. Like during christmas time would be a gud time to use this tool so that you can have the joy of seeing all the light.
The ISO tool has differnt levels the higher the level or number the brighter the lights will be. When you use flash it doesn't help your picture it just makes the whole area bright not the object you want it also takes away from myour photo. As to ISO it helps pop out bright colors and makes them easier to see.
It the photo the light is getting brighter as the ISO gets higher. It makes the natural light from the chrismas lights brighter then they are and makes the picture seem more clear.
