I'm reading some articles about pixels and I encountered this question.
First. When my photo is 20x20, and I'm seeing it at 100%, every pixel of photo is shown with every pixel of monitor.
When I zoom in, for example, 2000%, It's 20 times the 100% image. so every pixel of image occupies 20 pixel of monitor.
But What happens when you zoom-out? for example 50%. every two pixel of image occupies one pixel of monitor? If so, every pixel is capable of one solid color. not Two. Right? Can you explain it!?
