how does this work?
In: Physics
A blurry image happens when the light from the thing you want to see (or take a picture of) is coming in from a bunch of directions and angles. Lenses fix this by bending the spread out light and focusing it. Pinholes work by blocking out the light that isn’t coming in from a particular angle. It’s getting rid of the extra light that leads to a blurry image.
