Pixel Art and Other Bits

Hey everyone! Welcome to the second blog post! I should be updating this blog daily. Expect a lot of content ūüėÄ Hopefully you enjoyed the last blog post about how we can convert and image to a series of characters called ASCII art. Today I will be talking about exactly what a pixel is and what it can do. I’ll also clear up the misconception of what an 8-bit image actually is. Enjoy!

The screen I am viewing, to type this blog post, contains¬†2,073,600¬†pixels! If I counted my secondary screen, times our original screen by 2. Now I have¬†4,147,200 pixels… That may sound absolutely absurd, but it could never compete against our complex¬†optic nerves.

Here is a picture of shiny, red apple.


Here is the same shiny, red apple.¬†However, I have reduced the amount of pixels that this apple will use to represent itself.¬†This apple is now a¬†Low¬†Resolution. You can see how the apple appears blurry, or it doesn’t represent the original apple as well. That’s because it really is missing some of the original; a lot actually.

This apple right here is the same apple. This is what your image will look like with non-blurred pixels. It appears to look like a sprite in an earlier Final Fantasy game.

Pixels can be very useful for a game artists.

In the digital world, pixels are a physical point in an image. A pixel is the smallest, controllable display in the system. One pixel contains a code, a string of¬†0¬†and¬†1. These two numbers work in binary to tell the little pixel that it’s going to be blue, and that blue pixel is going to be softer in intensity; just like a pixel in the blue logo for WordPress.

Before our display hardware became as good as it is today, it looked quite a lot different.

Binary Image:

Just like every image in a digital format, a binary image is an image that contains pixels. These pixels use the binary code of 0 and 1, to determine if the pixel is black or if the pixel is white.

8-bit Grayscale Image:

In an 8-bit grayscale image, each pixel consists of 8 bits which make up 1 byte. These pixels are able to choose between 256 shades between black and white. In earlier hardware, grayscale images looked much like a binary image. This is because each pixel was 4 bits, allowing for only 16 shades between black and white.

Pixels are the foundation of digital art and game design. If your pixels are off, your art looks off. Take care about what type of image you create, because each kind can have a different effect. Thanks for reading and have a good day!
