Procreate is a raster graphics editor app for digital drawing and painting.
The aim of Procreate is to recreate the natural feel of physical drawing, while utilizing the practical advantages of a digital platform. It offers over 130 brushes, multiple layers, blend modes, masks, 4K resolution export of process videos, autosave, and many other digital art tools.
The following videos are a series created by YouTube creator: Art and Design. They are an excellent instructional baseline for how to use Procreate on the iPad. The first video video is a brief overview of the entire program. I have also included his 10 part series that goes into great depth of the major parts to Procreate.
