Why does this photo look like this?
High ISO is not the enemy. It is the tool that lets you keep a shutter speed fast enough to avoid blur when there is simply not much light.
Look at this
Grain is clearly visible and the finest texture is softened — but the photo is sharp and usable.
What would change with different settings
If you have a tripod and a still subject, a slower shutter at ISO 400 would be cleaner. For people who move, ISO 3200 is the better choice.
