Picture Element

Today I am posting for one of my assessments for college, I'm starting on "Pixels". alright, first up is:

Picture Element:

Picture elements are pixels (in a nutshell) these tiny, tiny, little squares make up pictures, as a collective pixels make up every raster graphic image out on the internet, a good way to show a pixel is to show you this picture.

 Here this picture shows pixels as it shows the image really close up. Pixels can be used to make shading on images, to make cartoon like images and to add very fine detail, when zoomed out, a raster graphic image will look really detailed and smooth, but closer up you will see the pixels.
