Why does this photo look like this?
Raising the ISO amplifies the signal from the sensor. The photo gets brighter without changing shutter or aperture, at the cost of a little grain.
Look at this
The scene is comfortably bright. Fine grain appears in the dark corners, but detail is intact.
What would change with different settings
This is usually the right trade: a slightly grainy sharp photo beats a clean blurry one.
