Why Do Newspaper Pictures Turn Into Tiny Dots Under a Magnifier?
Newspaper photos are printed with tiny dots of ink in different sizes. From far away, your eyes blend the dots into smooth shades. Up close with a magnifier, you can see the dots!
More fun facts
- Printed pictures are made of tiny dots that blend together when seen from normal distance.
- These are called halftone dots.
- Printers make shades by using dots of different sizes.
- Smaller dots look like lighter gray, and bigger dots look darker.
- Newspaper soaks up ink, which makes the dots spread bigger; this is called dot gain.
