ISO

In the first picture i used flash and this caused the picture to look really bright, and it's difficult to see the Christmas lights in the background. The second picture was taken with ISO5000 and this made the lights stand out and the person is also visible.t picture was taken with ISO50 and as you can see is extremely dark. The lights are visible but seem way to blurry and you cant even tell there's a person there! The difference between the three pictures is that flash just makes it bright but not great, and Low ISO is mainly used for too bright backgrounds not inside and the last ISO (5000) is made for this type of picture and looks the best.
