In this section I will be discussing the gradients, fills and the eraser in detail. Firstly, a gradient is a colour which gradually changes into another colour. There are different kinds of gradient shapes available in Photoshop for example: linear, radial, angular, reflected and diamond. You can also have more than one colour for a gradient which will allow you to create complex gradients with different colours.

The eraser tool allows you to remove pixels like a brush, and the fill tool is basically a way of pouring a flat colour onto a selected area.

Below is a preview of Gradients, Fills and the Eraser tools:
