Here pixels aren't constant, they're re-rendered whenever you change something. It's totally different with vector editors. What does it mean for us? To draw digitally in an editor like this, we need a tool created for traditional drawing - with its digital equivalent being a tablet pen.

Take the layers and undo's, and you've got a method identical with traditional drawing. Later these pixels can only be removed one by one (with an eraser) or covered with another splash, being lost forever (if it's the same layer). With every stroke you're creating a splash of pixels. In raster editors you draw with dots - no matter if it's a line, a square or a hyper realistic portrait of your cat, it's all dotted. The different methods of saving the content lead to different ways of drawing too. Newer versions of Photoshop have some vector options too, but you can't hide it wasn't really designed for this. When you move one of the points, the line is rendered once again without any loss. We can say a line is saved as start point, end point and its width. Vector programs (like Illustrator, Inkscape, CorelDRAW) save their files as a set of rules. After resizing it's not a pixel anymore - it's a square with visible, hard edges.

This set can't be changed without any loss in quality - when you resize a raster picture, every dot becomes bigger too. It means the picture is saved as a constant set of pixels. Photoshop (and Gimp, Paint.NET, PaintTool SAI, Microsoft Paint) are raster editors. Let's start with most obvious difference. And while Photoshop (and every other raster drawing software) favors tablet users, Illustrator doesn't mind creating with a mouse.

On the other hand, there exists another product of the same company - Illustrator. Drawing with a mouse is possible, but it's hard, time consuming and very frustrating. This software, although so popular and powerful, is designed to work with a graphic tablet. All these advantages are the reason why so many artists try their hands at Adobe Photoshop. You get so many colors, so many materials, every mistake can be fixed easily and it's all in a friendly, clean environment - you just need to turn off your computer afterwards. Creating digitally gives amazing possibilities.
