There are certain times when it’s dark, when it’s still best to refrain from using a flash. Look at this picture below. Here are my settings:
Camera setting = manual
ISO = 1000
aperture = 3.2
shutter speed = 1/160
And, how different would this picture have been with a flash? In my opinion not as good. This is real life. These are my little boys on a visit to the Aquarium. Not a photo shoot or anything fancy. Real life.
