Tablet Selection and Software
First and foremost, the tablet has become the most popular primary device for digital artists, and is the one the vast majority use today. Specifically, drawing tablets are those that come with specialized mouse options and pressure sensitivity, elements that might not be present in all tablets. Drawing tablets come both with and without screens depending on your needs.
In addition, and often chosen at the same time as your drawing tablet technology, the drawing software you land on is very important. Photoshop is the most popular and common option here, and has numerous features specifically for digital artists. However, if you do not have the budget for Photoshop, you can consider Coreldraw, Krita and others.
