How a computer reads a photo as an image file
Now that we have our data cleaned and separated, you might wonder how the computer reads these images.
Hint: Computers can't read images the same way humans do.
If you know something about developing for computers, you probably know computers read data in binary format. The data is represented as a long series of ones and zeroes like 101011001110001010111, and so on.
So, how can a computer read a complex image as only a series of ones and zeroes?
If you zoom in on the data in an image, you'll discover the picture in the photo is represented in the image file as pixels. Each pixel is a specific color that has a unique code. After the computer converts a photo into an image with these codes, it can read and decipher the binary pixel data.
Here's an example that shows how a computer transforms a photo into a series of numbers in an image file:
